Hey @abhi
Thanks for debugging this. As strange as it sounds, this error is present when the go test statement is in a separate RUN statement from the previous one. That is why I added it to the same statement earlier here Grpcerror by pawanrawal · Pull Request #79 · dgraph-io/dgraph · GitHub. I am guessing this is a problem with Docker though I didn’t file a bug.
How about you have it all as one RUN statement and set the GOROOT before it?
Just wanted to bring to your notice that for now we have checked in all our dependencies in the repo.
