I'm working on the hyperledger blockchain on Ubuntu 18-04 LTS via this tuto hyperledger.github.io/composer/latest/tutorials/developer-tutorial . I have installed all the pre-requisites and in this step of running "composer network install", I faced this issue and tried some solutions but still not working.
Any help please ? Thanks !
~/tutorial-network$ composer network install --card PeerAdmin#hlfv1 --archiveFile tutorial-network#0.0.1.bna
✖ Installing business network. This may take a minute...
Error: Error trying install business network. Error: No valid responses from any peers.
Response from attempted peer comms was an error: Error: Failed to connect before the deadline
Command failed
Docker ps and version
your fabric network is not running.
go to your fabric-dev-servers folder and run ./startFabric.sh
if you get any errors there, like some containers already exist then do a ./teardownFabric.sh first then run the start command again.
This will give you a basic running network with one org, one peer and one orderer.
Once your network is running then you need to create your admin card by running ./createPeerAdminCard.sh
only at this point you are ready to install and start your chaincode.
Just mentioning this for others who might face this issue - While in your case fabric network was not running, in my case it was an issue with proxy. Once I cleared that, I was able to deploy successfully.
I am trying to upgrade hyperledger fabric business network and I get this error
composer archive create -t dir -n . && \
composer network install -a $BNA_FILE -c PeerAdmin#hlfv1 && \
composer network upgrade -c PeerAdmin#hlfv1 -n NETWORK-NAME -V 0.1.23
The version number corresponds to that one in the package.json like the documentation says it should. I get the below error when I run the upgrade command
Error: Error trying to upgrade business network. Error: No valid responses
from any peers.
Response from attempted peer comms was an error: Error: 2 UNKNOWN: chaincode
error (status: 500, message: could not find chaincode with name 'NETWORK-NAME')
I made sure that hyperledger fabric is running ./startFabric yet I still get this error
The error message received is saying that there is no business network called NETWORK-NAME started. In order to upgrade a business network it has to have been previously started.
What it sounds like in this case is that you have started the simple fabric development server provided by composer and initially installed and started the business network NETWORK-NAME. At some point you have restarted the fabric but this restart has actually removed the existing fabric servers and created a new fresh fabric network. Because this is a clean fabric network, there now isn't a business network on the channel and you need to start again from scratch and install and start the business network. For example the startFabric.sh script actually completely removes your existing fabric network and creates a new one and as such the business network and data is lost.
These resources may help you if you want to look into ensuring your fabric server persists it's information under various circumstances.

since the recent upgrade I have trouble to start or deploy changes on my network. The commands : composer network start and composer network upgrade both give me this error message:
Error: Error trying to upgrade business network. Error: No valid responses from any peers. Response from attempted peer comms was an error: Error: REQUEST_TIMEOUT
I saw several posts with the same problem but no clear solution. The same thing is happening on the Playground UI when I want to deploy changes. I verified that I'm not behind a proxy or else. Thanks
Make sure that your peer is on by running docker ps
Check your docker ps list, make sure that there is no same version running to which you are upgrading. If so exist, delete it using
> docker stop containerId
> docker rm containerId
also before creating the archive file do not forget to set new version in package.json or you will get error like:
Error trying install business network. Error: The business network
is already installed on all the peers
I have run IBM marbles demo for implementing blockchain mentioned in below link:
https://github.com/IBM-Blockchain/marbles
When I have run Hyperledger Fabric and Marbles application on the same system(Ubuntu), it is working.
But when I have tried to run Hyperledger Fabric and client-side marble application in two different systems (one ubuntu and the other windows), it is not working.
Network script is running properly on Ubuntu.
And I also have changed in blockchain credential file by replacing localhost to IP address on which we need to run marbles application.
But when I am running chaincode installation script by running "node install_chaincode.js", it is giving an error as below :
error: [client-utils.js]: sendPeersProposal - Promise is rejected: Error: Connect Failed error: [fcw] Failed to obtain endorsement for transaction. code=14, error: [fcw] Error in install catch block object code=14
Can anyone provide me the solution or any reference link?
Thanks in advance.
I'm trying Hyperledger Composer v0.16.0. According to this procedure, I want to Deploy BNA to Fabric network on cloud. but following error occurs.
Kindly let me know how I can solve it.
command:
composer network start --card PeerAdmin#myfabric --networkAdmin admin --networkAdminEnrollSecret adminpw --archiveFile trade-network.bna --file networkadmin.card
result:
tarting business network from archive: trade-network.bna

Error: Error trying to instantiate composer runtime. Error: No valid responses from any peers.
Response from attempted peer comms was an error: Error: chaincode error (status: 500, message: chaincode instantiation policy violated(Failed to authenticate policy))
Error: No valid responses from any peers may be b/c you don't ./startFabric (in fabric-tools folder) or may be the .acl file (permissions.acl) have error (try change it to the beginning version).
The error 'Error: Error trying to instantiate composer runtime.' Suggests you have not run the composer runtime install command e.g.
composer runtime install -c PeerAdmin#fabric-network -n tutorial-network
Or that the command did not complete successfully.
The other possibility is that your fabric has stopped or is not contactable.
The runtime must be installed on fabric for the network to start.
"composer runtime install -c PeerAdmin#hlfv1 -n "
The Steps:
1) ./startFabric.sh,
2) ./createPeerAdminCard.sh,
3) composer runtime install -c PeerAdmin#hlfv1 -n ,
4) composer network start -a ./#0.0.1.bna -A admin -S adminpw -c PeerAdmin#hlfv1
there seems to be some challenges / bug with the use of composer
Composer Updates : 0.19.0 Changes:
End of March developers of Composer framework released version 0.19.0. Although there are multiple new features (mostly under the covers) in this release, it also introduced some BREAKING changes :( So what does that mean? It means that:
Some of the composer CLI commands have become obsolete or have changed
BNA Installation commands have changed ( install + start )
Following Composer CLI commands have been removed
runtime install, network deploy, network update, network undeploy
BNA upgrade requires an install of new version followed by
Composer card commands standardised to use -c or --card. Earlier some commands used -n and some used -c
Some of the Composer API have changed
That error can mean that the identity you are using to perform a network start doesn't have channel admin authority and thus is not authorised to perform a network start. I would suggest you check with whoever created your Hyperledger Fabric environment and channel to find out who the right identities are for administrative authority on the channel and build a card with the appropriate crypto material representing that identity in order to perform a network start.
1. ./stopFabric.sh
2. export FABRIC_VERSION=hlfv11
3. ./startFabric.sh
4. ./createPeerAdminCard.sh
5. install network
6. start network
Please create a new card with your business network name. Hopefully it will work:
composer network start --card PeerAdmin#myfabric --networkAdmin admin --networkAdminEnrollSecret adminpw --archiveFile trade-network.bna --file trade-network.card
I came up with a solution to my problem, which is similar to yours, it might be useful to you too:
I noticed that with other networks it works properly so, there is a problem with the DNS:
Edit or create /etc/docker/daemon.json in your machine and add:
{ "dns": ["your dns", "8.8.8.8"] }
Stop Fabric, restart Docker, Start Fabric
Repeat composer install and composer start
Well i was getting the similar error :-
Upgrading business network definition. This may take a minute...
Error: Error trying to upgrade business network. Error: No valid responses from any peers.
Response from attempted peer comms was an error: Error: 2 UNKNOWN: chaincode error (status: 500, message: could not find chaincode with name 'airlinev9')
Command failed
My composer version: v0.19.4
What I was trying to do:-
I was trying the update my BNA to a newer version. But got the error which i shown you above.
What I did to solve the issue :-
I first deleted the previous card using the command :-
composer card delete -c admin#airlinev9
And then start the BNA with (already created, installed):-
composer network start -c PeerAdmin#hlfv1 -n airlinev9 -V 0.0.3 -A
admin -S adminpw
And it worked for me.
I am SUPER new to HyperLedger hence I am not sure on how it worked out me but just in case might work for you too so try it out. I did only 2 things((on fabric-tool directory) :
1) ./startFabric.sh
2) ./createPeerAdminCard.sh
Ok I agree I lied. Not 2 things but 3.
3) Retry .bna association as expected normally.
I hope it works for you too :)
