I am gettting the following error when running the Lab 6.1 step: peer chaincode query -n reports -C mychannel -c '{"Args":["getAnnualReport", "2019"]}' -o orderer.example.com:7050

-- Error ---

Error: endorsement failure during query. response: status:500 message:"unable to perform a rich query using the query string {\"selector\":{\"date\":{\"year\":2019}}, \"use_index\":[\"_design/indexYearDoc\", \"indexYear\"]}: GET_QUERY_RESULT failed: transaction ID: 9792d735c41af848b09a39fa642f1b45c9fef4d4c876c6866d530a853e39919a: ExecuteQuery not supported for leveldb"

I run command

    @jjsull1van , Hi Jim, It looks like it is having issue with creating records in the ​Init​ function to populate the ledger with the initial data. When you finished adding records did you receive the "return​ shim.​Success​(​nil​)" Statement?

    Is there a step to call the function to populate the records? I do not see a separate step. I only see the query

    It looks like the records are populated in the Init function. Dose the Init run automatically on the install? My install successfully runs.

    I mean instantiation runs the Init function. My Instantiation runs fine.

    The install ran successfully
    The instantiate ran successfully. This is where the Init runs and adds the new records.
    The query returns an error

    Hi @jjsull1van,

    Your error message states that rich queries are not supported by LevelDB. Make sure you followed the prerequisites for the lab correctly and started a network with CouchDB enabled as a state database.

    The exercise is based on basic-network, so check basic-network/docker-compose.yml file. It should define all CouchDB-related variables under peer1's environment section:

    peer0.org1.example.com:
    container_name: peer0.org1.example.com
    image: hyperledger/fabric-peer
    environment:
      # <...>
      - CORE_LEDGER_STATE_STATEDATABASE=CouchDB
      - CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS=couchdb:5984
      - CORE_LEDGER_STATE_COUCHDBCONFIG_USERNAME=
      - CORE_LEDGER_STATE_COUCHDBCONFIG_PASSWORD=
      # <...>

    Best regards,
    Ilya
