Hyperledger Fabric 2.3 and Caliper V0.5 Issue

`I am not able to test my fabric 2.3 test network by using Caliper V0.5

Hi I am using fabric 2.3 test-network and testing performance with Caliper v0.5. I am also getting similar errors like.

No valid responses from any peers. Errors: peer=undefined, status=grpc, message=Peer endorsements do not match

Failed to submitTransaction, No valid response from peers

All fabric components are UP and running. Is there any issue with my configuration files. I am sharing my benchmark and network configuration. Please see and suggest the solution.'

My Caliper Benchmark Configuration is as follows:

test: name: basic-contract-benchmark description: test benchmark workers: number: 2 rounds: - label: readAsset description: Read asset benchmark txDuration: 30 rateControl: type: fixed-load opts: #tps: 25 transactionLoad: 2 workload: module: workload/readAsset.js arguments: assets: 10 contractId: basic My Caliper Network Configuration is as follows: name: Calier test version: "2.0.0"

The error message Peer endorsements do not match implies that a transaction proposal was submitted and to satisfy the endorsement policy it was sent to more than 1 peer. Responses from all the peers were received and they did not match (they should be identical). This message isn't a caliper message but a fabric message and thus is not a problem with caliper, but more likely the chaincode you are testing is not deterministic. I would suggest reviewing the hyperledger fabric documentation about chaincode determinism, but examples code in chaincode that are likely to make it non-deterministic are

  1. getting the current date and/or time
  2. generating a random number

chaincode that does this is going to be non-deterministic is you use these values to generate keys or form part of a property (2 peers running the same code are going to generate different values)
