body: <p>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 &quot;text/plain&quot;. Strict MIME type checking is enforced for module scripts per HTML spec.</p>
  <p>can anyone tell me the possible fix for that?</p>
