Testing pm2 vs deno in cluster does not work

Testing deno with load balancing, I setup an ec2 instance with node, pm2 and deno installed. Pm2 fails using below config.

module.exports = {
  apps : [{
    name: 'app',
    script: '/home/ec2-user/test/app.ts',
    interpreter: "deno",
    interpreter_args: "run --allow-env --allow-net --allow-read --allow-sys",
    instances: "max",
    exec_mode: "cluster",
	  increment_var : 'PORT',
    env: {
      "PORT": 8000,
      "NODE_ENV": "development",
    },
  }]
};

From logs:

Error: Cannot find module '/home/ec2-user/test/run'

  code: 'MODULE_NOT_FOUND',
  requireStack: []
}

For some reason, the interpreter option is ignored in the config file as pm2 keeps trying to exec run using node. I have tried using absolute path in the interpreter as well to no avail. Running from CLI on a single cpu works pm2 start app.ts --interpreter="deno" --interpreter-args="run --allow-env --allow-net" . Running from CLI with added -i max also fails.

Is this wai? or am I missing smthg? Seems like clusters do not work with deno...

Start with the shown PM2 ecosystem configuration and app.ts, then reproduce the working single-CPU command and the failing -i max cluster command. Compare the generated process invocation with the log showing Node trying to load run. Done means cluster mode correctly honors the Deno interpreter and arguments, or the limitation is clearly documented.
