I was trying to connect the composer bna to IBM blockchain, and I tried out installing grpc 1.9.1.. and even 1.10.1.. I tried out like everything, and the only thing that worked was doing as Kataus suggested, I commented out the lines relate to the getConnectivity state, and it finally connected to the IBM blockchain network I had.

I'm still getting below error after commenting the line in EventHub.js

Failed to invoke successfully :: TypeError: Cannot read property 'getConnectivityState' of undefined

Previous detailed error:

Yes, this is due to a new version of grpc released 3 days ago (v1.11.0). The version is controlled by fabric-client and it takes the latest available. You need to delete the grpc module and reinstall it with npm install [email protected]. This will fix the issue. Going forward you may need to have grpc fixed at 1.9.1 in your package.json until Hyperledger resolve this issue.

I commented these lines in EventHub.js. It's required only for state log. For example:

<br/>
<i>         var state = -1;<br/>
            //if(self._stream) state = self._stream.call.channel_.getConnectivityState();<br/>
            logger.debug('on.data - grpc stream state :%s',state);<br/>
</i><br/><br/>

it works fine now.
