Answer 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).

Answer 2

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

Answer 3

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

Answer 4

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 :)

Answer 5

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.

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
