Hi David, That's correct! However, we found a minor fix in the chaincode and post that the latest error logs give following stack trace: ``` [34m2021-01-12 09:22:03.362 UTC [endorser] callChaincode ->

Your first log snippet showed CouchDB queries timing out after 35 seconds each. This is the core.yaml ledger.state.couchDBConfig.requestTimeout of 35s. It means that CouchDB is still processing the qu

Thanks a lot David for your response. So digging deeper into the logs, we found that peer was returning below error: [chaincode] BuildQueryResponse -> ERRO Failed to get query result from iterator [ch

Adding workarounds such as longer timeouts will only prolong your pain. You must address the root cause of the slow query in CouchDB. Troubleshoot it in a separate CouchDB environment until you have f

Hi David, The chaincode is performing a select query on the CouchDB documents, and the fields set for filtering the results are indexed while installing and instantiating the chaincode. The single que

Thanks. chaincode-go has the same API, shim.GetMSPID(), which returns the value of env CORE_PEER_LOCALMSPID.

Hi, If I get your questions right, you want to fetch the MSPID of the peer that starts/endorses the chaincode. For that purpose you can use the chaincode shim API. In case it is java based chaincode y

The query appears to be a JSON find query. These queries will be slow or time out if they do not utilize a well designed index against the JSON data. See the CouchDB tutorial for more details: https:/
