Error run .mjs file

What's going wrong?

When I run pm2 start index.mjs -e logs/err.log I get an error

PS C:\Users\yuriy\Documents\Projects\testpm2> npm -v

PS C:\Users\yuriy\Documents\Projects\testpm2> node -v

index.mjs

import express from 'express';
const app = express();
const port = 3000;
app.listen(port, () => console.log(`App running on port  + ${port}`));

ecosystem.config.mjs

export const apps = [

    name: 'myapp',
    script: './index.mjs',
    watch: true,
    env: {
      'PORT': 3000,

  }
];

How could we reproduce this issue?

$ pm2 report
pm2 report doesn't work on windows 10 

Reproduce with the provided index.mjs, package.json, and ecosystem.config.mjs using pm2 start index.mjs -e logs/err.log on the reported Node.js version. Start at lib/ProcessContainerFork.js:78 from the stack trace and compare the direct and ecosystem launch paths. Done means the .mjs entry point starts without ERR_REQUIRE_ESM; separately verify the reported pm2 report behavior on Windows 10.
