I set up channel that has following compatibility, (set in configtx.yaml)
Capabilities:
Channel: &ChannelCapabilities
V1_3: true
Orderer: &OrdererCapabilities
V1_3: true

V1_3: true
and started the orderer with well generated genesis block file. I also specified orderer image version:

and it gives error

What should I do to fix this error? What I want to achieve is setting up a network that's only compatible with Hyperledger Fabric 1.3 nodes.
I tried with orderer capability V1_2 and it gives same (except version string) error. Does this mean capability version independent to Hyperledger Fabric version?
In HLF 1.2 & 1.3, the orderer still only supports V1_1 capabilities. So, your configtx.yaml should be:
Capabilities:
Channel: &ChannelCapabilities
V1_3: true
Orderer: &OrdererCapabilities
V1_1: true
Application: &ApplicationCapabilities
V1_3: true

I want to try the idemix feature introduced by Fabric 1.3 version. based on the repo. I did some changes in order to support idemix. But when I run java -cp blockchain-client.jar org.example.chaincode.invocation.InvokeChaincode
,btw, I omitted the step 5 for Register and enroll users, I came across

I set up a fabric network with minimal components. Two organizations, each has two peers and a CA. The demo is from repo. The demo's network with no idemix feature supported works well. When I add idemix section to configtx.yaml, regenerate crypto material, create a channel, etc. And the network finally is up. All containers are work well. But I interact with fab car chaincode using java-sdk, the above error info was thrown.
The following are from configtx.yaml file(just show key parts here):

The code I add in InvokeChaincode.java before creating channel client as follows:
// org/example/chaincode/invocation.java
UserContext normalUserContext = new UserContext();
String name = "user"+System.currentTimeMillis();
normalUserContext.setName(name);
normalUserContext.setAffiliation(Config.ORG1);
normalUserContext.setMspId(Config.ORG3_IDEMIX_MSP);
String enrollmentSecret = caClient.registerUser(name, Config.ORG1);
normalUserContext = caClient.idemixEnrollUser(normalUserContext, enrollmentSecret,normalUserContext.getMspId());
FabricClient fabClient = new FabricClient(normalUserContext);
The configuration file added code:
// org/example/config/Config.java
public static final String ORG3 = "org3";
public static final String ORG3_IDEMIX_MSP = "idemixMSPID1";
And docker-composer.yaml file remains unchanged.
All the images used are 1.4.1
I expect the endorser peer able to verify tx proposal from client with idemix enabled. But now the peer side report 2019-10-18 03:20:10.312 UTC [protoutils] ValidateProposalMessage -> WARN 049 channel [mychannel]: creator certificate is not valid: Failed verifing with opts [&{<nil> <nil> [] [{1 [111 114 103 49]} {2 1} {0 <nil>} {0 <nil>}] 3 [] 0 0xc00000fab8 0}]: signature invalid: APrime and ABar don't have the expected structure

I don't know why. I guess that if a peer does not support idemix tx verification. Are there some switches not open on peers? Help. Any replies will be thankful.
I'm trying to figure out how fabric-sdk-go works.
I created a connection with hyperledger, installed chaincode, but when I try to execute the request for some reason I get an error.

I found the solution to this problem.
I had to fix two issues inorder to get this working.
I was missing a few environment variables for TLS in my helm setup for orderer.
ORDERER_GENERAL_CLUSTER_CLIENTCERTIFICATE: "/var/hyperledger/tls/server/pair/tls.crt"
ORDERER_GENERAL_CLUSTER_CLIENTPRIVATEKEY: "/var/hyperledger/tls/server/pair/tls.key"
ORDERER_GENERAL_CLUSTER_ROOTCAS: "/var/hyperledger/tls/server/cert/cacert.pem"
Syntax error in configtx.yaml YAML config. I was repeating Consenters key multiple times.
while using the configtx.yaml from official Hyperledger repo we get below error when trying to create a genesis block:

How can we fix this please?
Solution is to delete the EtcdRaft section as the Raft based consensus is not yet implemented in Hyperledger Fabric v1.3 or 1.4. The configtx.yaml in the repo should not be having this section.

i'm able join channel but when i try updating anchor peer in channel
peer channel update -c settlement -o orderer.billerxchange.com:7050 -f billerxchangepeer.tx
i updated peer0 as anchor peer peer0 will get update and all the other peers in the network will crash. only peer0 remains up rest all peer containers are stopped or exited. I've attached container logs please check.
