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))

回答1:

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).

回答2:

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.

回答3:

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

回答5:

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.

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 :-

1. I first deleted the previous card using the command :-

composer card delete -c admin@airlinev9

2. 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.

回答7:

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:

1. Edit or create /etc/docker/daemon.json in your machine and add: { "dns": ["your dns", "8.8.8.8"] }
2. Stop Fabric, restart Docker, Start Fabric
3. Repeat composer install and composer start

回答9:

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 :)

回答10:

 1. ./stopFabric.sh
 2. export FABRIC_VERSION=hlfv11
 3. ./startFabric.sh
 4. ./createPeerAdminCard.sh
 5. install network
 6. start network
