@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?
0 -
Is there a step to call the function to populate the records? I do not see a separate step. I only see the query
0 -
It looks like the records are populated in the Init function. Dose the Init run automatically on the install? My install successfully runs.
0 -
I mean instantiation runs the Init function. My Instantiation runs fine.
0 -
The install ran successfully
The instantiate ran successfully. This is where the Init runs and adds the new records.
The query returns an error~/go/src/github.com/hyperledger/fabric-samples/first-network$ docker exec -it cli bash

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 checkbasic-network/docker-compose.yml
file. It should define all CouchDB-related variables underpeer1
'senvironment
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,
Ilya0
