Error while performing "test" step: Error: Multiple bindings for fabric have been detected, you need to unbind one or more to ensure only a single bind is present to continue

[umitkilic]

Which Caliper version are you using?

0.6.0

Which Node.JS version are you using?

v20.18.1

Which operating system are you using?

Ubuntu 22.04

Please provide some context for your error. For example, when did the error occur? What were you trying to achieve, and how?

I was trying to run caliper on my HyperledgerFabric v3.0.0 network. I bind just fabric:2.4 with command but it always says there is a multiple bindings. What is the problem and solution?

What was the observed incorrect behavior?

Caliper says there is multiple bindings and benchmark execution failed with error code 6

Please provide the error logs and their surroundings.

Please provide any additional information you deem relevant to the error.

Under node_modules folder, I have @hyperledger folder and under it, there are four folders (named caliper-cli, caliper-core, caliper-ethereum, caliper-fabric, fabric-gateway, and fabric-protos). The first four folders were downloaded after npm install command. The last two ones were downloaded after I typed npm install --save @hyperledger/fabric-gateway@^1.5.0

Maybe there is something that I overlooked, I unbinded all version by changing version number in caliper unbind --caliper-bind-sut fabric:X.X command. I tried binding only 2.4 but it does not work.

@umitkilic Have you checked out the caliper tutorial for hyperledger fabric ? It shows how to install caliper and bind to fabric gateway so I would suggest you follow that path

I completely rebuilt the Fabric network and followed the exact same steps as described on the site, but I still get the same error.

I am writing this for those who will encounter this problem in the future. This solution led me to another problem but it does not give this error anymore. The problem is caused by the inability to isolate some files when working with more than one hyperledger fabric version. When I tracked the source of the error, I saw that the fabric-network folder in the node_modules folder caused this error. Because it is not used in Hyperledger Fabric v2.4 and later versions (https://www.npmjs.com/package/fabric-network) and Fabric Gateway needs to be used instead. If you delete the relevant folder or adjust your runtime environment accordingly, this problem will be solved.

@umitkilic If you install node modules globally then you will encounter issues if you then use the same node install to run caliper. This is why caliper advocates using npx with local installs of caliper and bindings so you don't store anything globally and in fact this is a better approach overall when using node. Caliper can drive 3 different fabric client sdks, and if it detects more than 1, which one should it use ? For benchmark runs you need to have a consistent setup to ensure benchmarks are comparable. The only time you want benchmarks from different bindings to compare is when comparing the performance of the SDKs themselves and they do perform differently.
