From the code snippet, I assume you are sending a single CSV file to your chaincode, then looping through it and calling PutState for each line/record in the CSV file. I do not think you are actually

configtxlator does not stdout with node SDK ('child_process').exec
#fabric-sdk-node
You may start configtxlator as a server, and invoke its functions as REST APIs. This is the preferred integration option for Node SDK -- see https://fabric-sdk-node.github.io/tutorial-channel-create.h

Hi, From Node SDK, is there anyway to get stdout from configtxlator as it is possible in shell ? It seems that the --output option can not be omitted using (child_process) exec. Thanks a lot for you h
