Remove JavaScript Source Maps

[Scarbous]

Please remove //# sourceMappingURL= form generated JS Files or add the map files.

Because it leads to the following behavior:

When I use my DevTools tons of errors like: DevTools failed to load source map: Could not load content for ....js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

This leads to the following error:

actions.js:105 Uncaught TypeError: Cannot read properties of undefined (reading 'map')
    at UiClass.updateActions (actions.js:105)
    at setNested (objects.js:44)
    at Object.nested (objects.js:118)
    at UiClass.set (element.js:305)
    at updateValue (links.js:80)
    at events.js:86
    at Array.forEach (<anonymous>)
    at trigger (events.js:83)
    at UiClass.trigger (events.js:161)
    at UiClass.<anonymous> (element.js:424)

I use Chrome, when I disable Enable JavaScript source maps in the DevTools Settings the error is gone.

Having nearly the same result on M.2.4.4 with PageBuilder 2.2.2. Lot of sourcemap files are not generated at the adminhtml.
