Failed to load module script: The server responded with a non-JavaScript MIME type of "text/plain". Strict MIME type checking i

Question

while building a debug toolbar in Django I am getting an error in file toolbar.js ie. s.map: HTTP error: status code 404, net:: ERR_UNKNOWN_URL_SCHEME toolbar.js:1 Failed to load module script: The server responded with a non-JavaScript MIME type of "text/plain". Strict MIME type checking is enforced for module scripts per HTML spec.

can anyone tell me the possible fix for that?

I used Django Debug Toolbar and try to build a Django debugger by taking references from some articles, documentation, and video tutorial. — Nkgupta
Ok, in the meantime we need more information to help you. Is that toolbar.js file was created by you or it's the part of DDT (django debug toolbar)? Also, we should take a look on your template where you add that file. Please add the required information to your question. — Dmitry Belaventsev

I found solution here How to set content type of JavaScript files in Django

#settings.py
if DEBUG:
    import mimetypes
    mimetypes.add_type("application/javascript", ".js", True)
