Been learning a bit about both Hyperledger Fabric and Hyperledger Caliper recently.
Recently have been following the Hyperledger Caliper Fabric benchmarking tutorial here to learn a bit more about it.
It uses the Fabric Samples network as an example with the sample chaincode used being the asset-transfer-basic javascript.
When running caliper for creating 1000 assets for example.
I get an occasional error initializing the test during the asset creation operation, like this:
2021-05-05T21:28:58.344Z - error: [DiscoveryHandler]: compareProposalResponseResults[undefined] - read/writes result sets do not match index=1
2021-05-05T21:28:58.344Z - error: [Transaction]: Error: No valid responses from any peers. Errors:
peer=undefined, status=grpc, message=Peer endorsements do not match
2021.05.05-22:28:58.344 error [caliper] [connectors/v2/FabricGateway] Failed to perform submit transaction [CreateAsset] using arguments [0_231,blue,20,penguin,500], with error: Error: No valid responses from any peers. Errors:
peer=undefined, status=grpc, message=Peer endorsements do not match
The sample chaincode operation is pretty simple:
// CreateAsset issues a new asset to the world state with given details.
async CreateAsset(ctx, id, color, size, owner, appraisedValue) {
const asset = {
ID: id,
Color: color,
Size: size,
Owner: owner,
AppraisedValue: appraisedValue,
};
ctx.stub.putState(id, Buffer.from(JSON.stringify(asset)));
return JSON.stringify(asset);
}
Is there any particular reason errors like this happen? Even if occasionally.
