Dash 0.35.2 to 0.39 --- CHROME: Refused to execute LOCAL script because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled

Dash Python

Hello there! This is my first post so, first of all, thanks for all the work you are putting on this, really amazing tool!

I’m in the process to update an existing app from dash 0.35.2 to 0.39, and after bumping versions Chrome suddenly stopped loading local javascript files (works on IE and Firefox), with the error message:

Refused to execute script from '...' because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled.

I thought this might be because the generated tags do not declare types, but all other dash js are being loaded so I don’t think it’s this. I’ve also looked for similar issues affecting dash without luck, so I thought I might get some help posting this here!

Any idea why this is happening now? Has something changed in these versions that could generate this issue? I don’t think so by looking at the changelog, but maybe someone has encountered something similar…

Thank you very much!
