    @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
