Thank you in advance!

@FabianChiera ,

Hello , This forum is to assist learners with the LFD272 coursework. Is the example you are referring to in the user documentation? Bobbi

Hi @FabianChiera,

Make sure that the environmental variables are set in the same command as a binary execution:

CORE_PEER_ADDRESS=peer:7052 CORE_CHAINCODE_ID_NAME=mycc:0 ./chaincode_example02

If you'd like to utilize these variables through the whole terminal session, you can instead try to export them:

export CORE_PEER_ADDRESS=peer:7052
export CORE_CHAINCODE_ID_NAME=mycc:0
./chaincode_example02

Best regards,
Ilya
