Is it possible to create a hyperledger fabric channel or no?
i am asking this because i have been stuck for more than two weeks with this error:
Error: got unexpected status: FORBIDDEN -- config update for existing channel did not pass initial checks: implicit policy evaluation failed - 0 sub-policies were satisfied, but this policy requires 1 of the 'Writers' sub-policies to be satisfied: permission denied"
know that I use the correct path of the "MSP folder" of the admin "Admin#productionlaborg" how created the channel, but I get also in the logs of orderer docker container this error:
Invalid identity: certificate subject=CN=Admin#productionlaborg.supplychain.com,OU=admin,L=San Francisco,ST=California,C=US serialnumber=209542001001378907007459857235386288226 error="the supplied identity is not valid: x509: certificate signed by unknown authority (possibly because of "x509: ECDSA verification failure" while trying to verify candidate authority certificate "ca.productionlaborg.supplychain.com")"
PLEASE I NEED HELP
I had created a network with two organization(Org1,Org2) in the channel using the fabric version 1.4.4.I have added one more organization to the channel.After adding the new organization to the channel,I am trying to update anchor peer based on this reference https://hyperledger-fabric.readthedocs.io/en/release-1.4/channel_update_tutorial.html#updating-the-channel-config-to-include-an-org3-anchor-peer-optional .
But it raises error while trying to sign the update transaction using Org3.
Error: got unexpected status: BAD_REQUEST -- error applying config update to existing
channel 'masterchannel': error authorizing update: error validating DeltaSet: policy for
[Group] /Channel/Application not satisfied: implicit policy evaluation failed - 1 sub-
policies were satisfied, but this policy requires 2 of the 'Admins' sub-policies to be
satisfied
I tried to sign the transaction using one more org(org 2) in the network. And it raises another error as follows.
Error: got unexpected status: BAD_REQUEST -- error applying config update to existing
channel 'mychannel': error authorizing update: error validating DeltaSet: invalid
mod_policy for element [Group] /Channel/Application/Org3: mod_policy not set
I am attaching the configtx.yaml regarding the Application capabilities.
Application: &ApplicationCapabilities
V1_4_2: true
V1_3: false
V1_2: false
V1_1: false
Could anyone help me to resolve the error in anchor updation?
The above errors are due to the invalid policy definition in the channel configuration.
The policies for the org is defined in configtx.yaml file as follows:-
Organizations:
- &Org3
Name: Org3MSP
ID: Org3MSP
MSPDir: 'crypto-config/peerOrganizations/org3.example.co/msp'
Policies:
Admins:
Type: Signature
Rule: "OR('Org3.admin')"
The anchor peer update is an update to Org3, so we only need the signature of the Org3's admin for the configuration update as per the policy defined in configtx.yaml file.
The mod_policy error was due to the invalid name for the Org3 we mentioned in the channel’s application groups field.
We have to use the name of the org we defined in the configtx.yaml file in the
channel’s application groups field.
I have replaced the name Org3 to Org3Msp(Org name in configtx.yaml) to resolve the error.
jq '.channel_group.groups.Application.groups.**Org3MSP**.values += {"AnchorPeers":
{"mod_policy": "Admins","value":{"anchor_peers": [{"host":
"peer0.org3.example.com","port": 11051}]},"version": "0"}}' config.json >
modified_anchor_config.json
When I try to create a channel using Hyperledger Fabric, the request fails and returns the following error:
Client logs:
Error: got unexpected status: BAD_REQUEST -- error validating channel creation transaction for new
channel 'testchannel', could not succesfully apply update to template configuration: error
authorizing update: error validating DeltaSet: policy for [Group] /Channel/Application not
satisfied: implicit policy evaluation failed - 0 sub-policies were satisfied, but this policy
requires 1 of the 'Admins' sub-policies to be satisfied
This error occurs when there is a problem with the identity (consisting of MSP ID, certificate, and keys) that submitted the request. If you use the default Fabric configuration policies, channels need to be created by organization administrators. The error is produced by your identity not being able to satisfy default policy on the /Channel/Application/Admins path.
There are several reasons why the policy would reject your identity, including the use of invalid or expired certificates. You can learn more about why the request failed by looking at your orderer logs. The Ordering Service is the node that enforces the policies that create or update channels.
When you examine your orderer logs, look for an error that is similar to what was returned to your client. You may find an error from a certificate check immediately preceding the policy error (Principal deserialization failure). This implies that the channel creation was rejected because the MSP ID was not recognized as valid.
Ordering Service logs:
2019-08-06 15:31:43.589 UTC [cauthdsl] deduplicate -> ERRO 021 Principal deserialization failure

update to template configuration: error authorizing update: error validating DeltaSet: policy for
[Group] /Channel/Application not satisfied: implicit policy evaluation failed - 0 sub-policies
were satisfied, but this policy requires 1 of the 'Admins' sub-policies to be satisfied
The error before the policy warning, ERRO 021 Principal deserialization failure (MSP SampleOrg is unknown) for identity 0, indicates that the MSP ID that was passed as a parameter with the request was not recognized by the ordering service. This could be a result of passing the wrong MSP ID to the command. This error may also indicate that your organization has not joined the consortium hosted by the ordering service system channel. If you are updating an application channel, this error could occur if your organization is not yet a member of the channel you are trying to update.
If the MSP ID of the identity is valid, you may encounter the following certificate validation error:
Ordering Service logs:
2019-08-06 15:34:45.730 UTC [cauthdsl] deduplicate -> ERRO 02d Principal deserialization failure
(the supplied identity is not valid: x509: certificate signed by unknown authority) for identity 0

update to template configuration: error authorizing update: error validating DeltaSet: policy for
[Group] /Channel/Application not satisfied: implicit policy evaluation failed - 0 sub-policies
were satisfied, but this policy requires 1 of the 'Admins' sub-policies to be satisfied
In this case, the ordering service recognized your MSP ID, but could not validate that your certificate was issued by one of your organization's certificate authorities. If you are managing multiple organizations, this error could be the result of you using a mismatched MSP ID and certificate to submit the request. This error could also occur if your admin certificates have expired. If this is a test network that has been launched recently, you may be issuing the request from an identity that was created by a certificate authority on an older incarnation of your network.
It will be more common that your certificate has passed the validation check, but could not fulfill the channel creation policy. If that is the case, the error in your orderer logs would look like the following:
Ordering Service logs:
2019-08-06 15:36:52.307 UTC [orderer.common.broadcast] ProcessMessage -> WARN 032 [channel:
testchannel] Rejecting broadcast of config message from 172.27.0.7:37236 because of error: error

update to template configuration: error authorizing update: error validating DeltaSet: policy for
[Group] /Channel/Application not satisfied: implicit policy evaluation failed - 0 sub-policies
were satisfied, but this policy requires 1 of the 'Admins' sub-policies to be satisfied
The identity that submitted the request is a valid member of your organization, and your organization is recognized to be a member of the system channel or application channel. However, the identity did not have the permission to create a channel. You may have used the wrong identity to submit the request, and used an identity that was not your organization administrator. Submit the request from your admin identity, or create a new admin, and have the channel administrator update your organization MSP.
If you encounter this error for operations other then channel creation, your certificate may not be authorized for the correct role. Check that your client certificates and peer certificates have the client and peer OU respectively.
Additional debugging techniques
If you need additional help debugging a policy or certificate related error, you can increase the logging level related to those components:
FABRIC_LOGGING_SPEC=”WARN:cauthdsl=debug:policies=debug:msp=debug
You can also manually pull your organizations root certificate from an application or system channel and use them to verify your client side certs. Use the following command to pull the latest configuration block from your channel.
peer channel fetch config ./configupdate/config_block.pb -o <orderer_endpoint> -c <my_channel> --tls --cafile <PATH_TO_ORDERER_TLS_CERT>
Then use the following command to convert the configuration block into JSON.
configtxlator proto_decode –type=common.Block --input=config_block.pb --output=config_block.json
This allows you to pull the root certificate from the block using the following command. Replace with the MSP ID of your organization.
jq -r .data.data[0].payload.data.config.channel_group.groups.Application.groups.<MSPID>\
.values.MSP.value.config.root_certs[0] config_block.json | base64 –decode > root.pem
If your MSP defines multiple root certificates or uses intermediate certificates, you will need to adjust the jq command above to properly extract them.
You can then use tools such as OpenSSL to validate your client side admin certificate against the root certificate.
openssl verify -CAFile <root.pem> <admincert.pem>
You can also use the following command to open the certificate and examine it in plaintext. This allows you to check fields such as the expiration date, the node OU, or the issuing CA.
openssl x509 -in <admincert.pem> -text

If you are getting aforementioned error then check your configtx file and verify below mentioned attributes. Copy paste the below section and replace capabilities section.
Capabilities:
# Channel capabilities apply to both the orderers and the peers and must be
# supported by both.
# Set the value of the capability to true to require it.

Also check your channel name
export SYS_CHANNEL=orgchannel #should be your own system channel name
export CHANNEL_NAME=org1orgchannel #should be your own system channel name
export CHANNEL_ID=org1orgchannel #should be your own system channel name
Also remember SYS_CHANNEL value should be different from CHANNEL_NAME. CHANNEL_NAME and CHANNEL_ID should be same.

Trying to add a new organisation from a separate host.(Modifying steps from ./eyfn.sh when necessary).
Managed to create and import network admin card using Hyperledger Composer. (https://medium.com/#mahoney_33893/hyperledger-composer-adding-another-organization-to-an-existing-running-multi-organization-fff5c8104a82).
However when pinging the network I got:
Error: Error trying to ping. Error: 2 UNKNOWN: access denied: channel [composerchannel] creator org [Org3MSP]
Upon getting the logs from peer I got
-Principal deserialization failure (MSP Org3MSP is unknown) for identity
-[channel: composerchannel] Client authorization revoked for deliver request from 10.0.1.6:48262: Failed evaluating policy on signed data during check policy on channel [composerchannel] with policy [/Channel/Application/Readers]: [Failed to reach implicit threshold of 1 sub-policies, required 1 remaining]
My problem is actually similar to that of Hyperledger-Composer: Getting "access denied" when pinging network admin card.
The solution did mention to include msp files of my new org into volumes of the orderer which I did as
docker cp msp <containername>:/etc/hyperledger/msp/peerOrganizations/org3.example.com
My first organisation was set up using the default ./startFabric.sh
Take note that im not using TLS for the time being.
The error still persist though and Im wondering why. I do however suspect that the way im giving msp to the orderer is somehow wrong. or Im putting it in a wrong file.
Maybe you will need to migrate from Composer to other framework.
Hundreds of devs are taking is using Convector. Convector is a Hyperledger Labs project that was created before Hyperledger Composer was deprecated but that looks similar to developers. It follows a model controller pattern (similar to Composer assets and transactions) however it compiles natively to Fabric code and does not create a runtime.
I am trying to config a hyperledger fabric network on aws.
I have 3 aws ubuntu instances and each is fabric-ca, fabric-orderer, fabric-peer latest docker image.
First, I started up my CA server with "start -b" command. I checked one identity is registered in CA server db.
After that, I started up my orderer server. After that enrolled CA registered identity on the orderer server and registered and enrolled orderer identity using fabric-ca-client bin. Finally I created genesis block using configtxgen bin.
The Problem is here.
I started up a peer and proceeded same steps mentioned above and created an identity type peer. After that I created admincerts directory and put a cert.pem in a ca signcerts directory. I though this certification file describes an identity created by CA.
But when I tried to create a channel to orderer, it says error authorizing update: error validating DeltaSet: policy for [Group] /Channel/Application not satisfied: Failed to reach implicit threshold of 1 sub-policies, required 1 remaining .
How can I make administrator certification for a peer to create a channel?
channel creation has many error prone areas
1). It could be that you are passing a wrong mspID.

Reason: transaction is not signed with admin key
Solution: To create a channel we need admin credentials such as private key & public certificate(Ex: x.509)
