Hyperledger Composer: Error trying to instantiate composer runtime.

0 votes

I'm using Hyperledger Composer [v0.18.2]

I try to start the network with "composer network start ...." i'm getting this error:

Starting business network definition. This may take a minute...
Error: Error trying to instantiate composer runtime. Error: No valid responses from any peers.
Response from attempted peer comms was an error: Error: 2 UNKNOWN: chaincode error (status: 500, message: instantiation policy violation: signature set did not satisfy policy)

Can someone tell me how to solve this?

It looks like a problem with composer-cli. 

A simple solution is to re-install it. 

Uninstall Composer completely

npm uninstall -g composer-cli

Then, install Composer v0.18.1

npm install -g composer-cli@0.18.1

This should work.
