run pm2 with ES modules

Question

How can i use pm2 in combination with a package based on ES Module (type:"module") I looked into similar Questions without any useful help (some say it does not work on windows, but i am using linux)

I always receive the error:

Error [ERR_REQUIRE_ESM]: require() of ES Module /opt/app/server/lib/src/index.js not supported.
0|any| Instead change the require of index.js in null to a dynamic import() which is available in all CommonJS modules.

My ecosystem.config.js looks like:

const os = require('os');
module.exports = {
    apps: [{
        port        : 3000,
        name        : "any",
        script      : "lib/src/index.js",
        watch       : true,           
        instances   : os.cpus().length,
        exec_mode   : 'fork',         
        env: {
            NODE_ENV: "production",
        }
    }]
}

index.js is a ES module using "import" syntax. How can i tell pm2 that is should use this way of importing

renaming ecosystem.config.js to ecosystem.config.cjs worked for me
