You posted a lot of source code snippets but did not actually describe the issue you are having.

I am having a problem running it in cluster mode. While the mode is working, I do not have any error logs, only information indicating that there is an error with the instance running in cluster mode.

Is that message appearing when you do pm2 logs? Or else, where do you see it?
Could it be that this happens because your script is completing/terminating? It doesn't seem to have any functionality that needs to be clustered.

Or another way, do you have any JS script that works with cluster mode? Can you share the repository with me, including the package.json file?

Code 0 is a normal successful program end, which I'd expect from the code you provided.
The cluster mode is meant to automatically share a listening port between all nodes in the cluster. For example if you setup an express server and want to load balance between multiple nodes. So perhaps the sample code of express might be a good test. Another example would be if you have built a (queue) worker. In any case scripts that keep running because they are listening on a port or waiting for an event to happen.
