 * Hello,
    Is there any way to get rid of missing JS source map DevTools warnings,
   without disabling the source map option in DevTools preferences? Couldn’t find
   anything about the source maps in AMP documentation.
 * DevTools trying to load following source maps: `ww.mjs.map` and `worker.mjs.map`

 * Hello [@egornmore](https://wordpress.org/support/users/egornmore/)
 * I will recommend ignoring that warning, A sourcemap is a mapping between the 
   generated/transpiled/minified JavaScript file and one or more original source
   files. The main purpose of sourcemaps is to aid debugging. Basically, if there’s
   an error in the generated code file, the map can tell you the original source
   file location. That’s it.
 * You can disable the warning by opening dev tool preference and unchecking Javascript
   Source map option ([screenshot](https://prnt.sc/H1BF_zas61sz))
 * Hope this helps!
