Docker image latest crashes on startup

Since the changes on October 24th, the docker image cannot start anymore:

node:internal/modules/cjs/loader:1228


  throw err;

  ^

Error: Cannot find module '/app/node'

    at Module._resolveFilename (node:internal/modules/cjs/loader:1225:15)

    at node:internal/main/run_main_module:28:49 {

  code: 'MODULE_NOT_FOUND',

  requireStack: []

}

Node.js v20.18.0

There are 2 reasons:

The node argument probably needs to be removed from the CMD line since the image already inherits the entrypoint /nodejs/bin/node, so the CMD should only be src/index.js.
The app itself is never copied into any of the images, only the package.json is. You removed most of the COPY lines which also includes copying the javascript files into the image, so the image only consists of node and npm dependencies.

Even after fixing both, the container still crashes with:

(node:1) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)
/app/src/index.js:2
import RssFeedEmitter from 'rss-feed-emitter';

Node.js v20.18.0

The reason why I renamed index.js to index.mjs 2 years ago was because of this error.
