[SingleQueryHandler]: evaluate: message=Query failed. Errors: [], stack=FabricError: Query failed. Errors: [] Hyperledger Fabric SDK 2.2

Question

I am running Fabric Node SDK 2.2. The issue I am facing while querying the ledger is this.

error: [SingleQueryHandler]: evaluate: message=Query failed. Errors: [], stack=FabricError: Query failed. Errors: []
    at SingleQueryHandler.evaluate (/fabric23/node_modules/fabric-network/lib/impl/query/singlequeryhandler.js:47:23)
    at Transaction.evaluate (/fabric23/node_modules/fabric-network/lib/transaction.js:276:49)
    at ContractImpl.evaluateTransaction (/fabric23/node_modules/fabric-network/lib/contract.js:179:45)
    at main (/fabric23/test.js:69:40)
    at processTicksAndRejections (internal/process/task_queues.js:97:5), name=FabricError
Failed to evaluate transaction: FabricError: Query failed. Errors: []

So I set the debug log location and found that the singlequeryhandler.js constructor is getting passed an empty list of peers. However before that the log shows that it was able to connect to all the peers and orderers in the network. Not sure if I am doing something wrong. Adding the *s around the constructor log line to make it spottable.

Any help is appreciated. Thanks.

Answer 1

This error is happening because the SingleQueryHandler was initialized without endorsing peers, as you can see in the log line

[SingleQueryHandler]: constructor: peers=[]

And the error log also doesn't help:

error: [SingleQueryHandler]: evaluate: message=Query failed. Errors: [], stack=FabricError: Query failed. Errors: []

But it's not your fault since that's how the library handles errors on evaluation. I made this fluxogram in order to facilitate understanding over why empty endorsing peers list is a problem.

Understanding that, i think that the error may be solved by following what this user did in this another post: Solved issue for finding peers in another organization

I've already sent a PR to their repositories to enhance their excpetion log error: PR for log error enhancement . Of course, it doesn't solve the errors, but it gives a better feedback to developers. I'm facing this issue too recently.
