pm2 logs isssue with nyc

I am trying to use pm2 to run a JS file with NYC.
The pm2 "exec_mode" is set to cluster "cluster", we have to use this configuration.

We run pm2 with the following config (ecosystem-run-nyc.json, attached):

{
    "apps": [
        {
            "name": "my-nyc-wrapper",
            "script": "node_modules/nyc/bin/nyc.js",
            "instances": 1,
            "exec_mode": "cluster",
            "shutdown_with_message": true,
            "args": [
                "node", 
                "index.js"
            ],
            "watch": false,
            "node_args": "--max_old_space_size=8192",
            "out_file": "logs.log",
            "error_file": "logs-error.log",
            "merge_logs": true,
            "env": {
                "NODE_ENV": "production",
                "NEWRELIC_APM_ENABLED": "false"
            }
        }
    ]
}

The problem is that the logs are not associated with the relevant log (by the service name).
Instead of that the logs write to the root pm2 logs.

if I run pm2 monit it looks like I don`t have any logs for this specific service.

I attached here here the full example to nyc-logs-error.zip

If I changed the mode to "fork" it works fine.
If I try to run the js without nyc it works fine too.

pm2 version : 5.1.2
node version : v16.13.0

thx

Start with the attached ecosystem-run-nyc.json configuration and reproduce the behavior using PM2 5.1.2 with Node.js v16.13.0. Compare cluster and fork modes, and runs with and without NYC; done means NYC output is associated with the service logs and appears correctly in pm2 monit rather than the root PM2 logs.
