ERRO 003 Error trying to connect to local peer: context deadline exceeded

Question

Following my previous question. I'm still trying to make the tutorial "Chaincode for Developers" work. It still does not work :

Terminal 2 - Build & start the chaincode, getting this error when running chaincode :

userChaincodeStreamGetter -> ERRO 003 Error trying to connect to local peer: context deadline exceeded

Answer 1

After coming across this issue, I checked which ports which were being used by "peer", and was surprised to see that the port in question, 7052, was not listed as a peer node port.

So, I updated to this command, i.e. changing port 7052 to 7051:

CORE_PEER_ADDRESS=peer:7052 CORE_CHAINCODE_ID_NAME=mycc:0 ./sacc

TO:

CORE_PEER_ADDRESS=peer:7051 CORE_CHAINCODE_ID_NAME=mycc:0 ./sacc

Following that change, startup seems to work correctly (although the behavior soon looks like a hung process, once the code was registered. Subsequent tutorial steps worked as expected.)
