ChaincodeServer grpc.max_receive_message_length and grpc.max_send_message_length arguments about fabric-chaincode-node HOT 3 CLOSED

Assuming this isn't a fabric-samples chaincode, is there anywhere else in the chaincode that might overwrite the grpc message length variables?

Hello @alexanderlamb

Firstly - could briefly describe what problem you ran into that means you need to up this limit? Where you sending a transaction function with a large payload?

Java Chaincode does seem to have these options available - it defaults to 100Mb for max-message-size.
This does need setting both sides I believe (based on grpc documentation).

Node chaincode has this missing I believe.

Hi @mbwhite,

Our payload size can become quite large yes. We're easily bumping up against the limit as it currently stands. As a temporary fix, we've forked this repo and bumped up the limit to 100Mb and can confirm its working.

Also, this may be a separate conversation, but this issue was discovered when stream.cancel() was being called when it no longer existed.
