Hyperledger-Composer: composer network start error:Error: REQUEST_TIMEOUT Command failed

Question

After I created a program and finished the model design/ query.qry / acl. I tested it at local playground and it ran successfully. When I tried to create the admin card (run composer network start), I failed. It launched a ccenv peer without response.

I couldn't find any other similar mistake in Google. It confuses me.

Expected Behavior Composer network start command should run successfully. And the admin card should created properly.

Actual Behavior Failed to create card. And launched a weird peer with a random name. When I try to run again:composer network start -n cmusic -c PeerAdmin@hlfv1 -V 0.0.1 -A admin -S adminpw It said that it's already been launched.

Possible Fix I don't know why and how to fix it. I tried reload the environment but the same mistake still exists.

Answer 1

I have solved this problem. The key is that there can only be one chaincode in the network at the same time. If you deploy multiple at the same time, this error will occur.

Try these two and restart the network.

docker stop $(docker ps -aq) docker container prune
