Source Map Error Modals and Alerts

Can anyone else please confirm this, it is being reported in Firefox for Mac

Console
Source map error: request failed with status 404
Resource URL: https://www.example.com/dmxAppConnect/dmxBootstrap4Modal/dmxBootstrap4Modal.js
Source Map URL: …maps/dmxBootstrap4Modal.js.map

Source map error: request failed with status 404
Resource URL: https://www.example.com/dmxAppConnect/dmxBootstrap4Alert/dmxBootstrap4Alert.js
Source Map URL: …maps/dmxBootstrap4Alert.js.map

I have the correct files in my directory structure for
dmxAppConnect/dmxBootstrap4Alert/dmxBootstrap4Alert.js √
dmxAppConnect/dmxBootstrap4Modal/dmxBootstrap4Modal.js √
but in the directory
dmxAppConnect/maps/
I do not have files for dmxBootstrap4Alert.js.map or dmxBootstrap4Modal.js.map

Can anyone confirm if they have these files in their map folder or if it just me please.
Also does anyone know if this is actually an issue or not, i have never really dealt with map files before so I really do not know.

Hey Paul,
Source .map files are only being used for our own debugging purposes, so depending on the browser used they are only called when the browser debug console is open, because the compressed source points to them and it wants to load them in developer inspector to show the uncompressed source.
So only if we want to debug issues with the script (which is compressed) we add them there, and they are only called if the console is open.
That is not a problem and there is nothing to worry about, they are not used by you website.

Thanks for confirming @Teodor, appreciate it.
