Error while setting up: main_bundle.js was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff)

Hey, thanks for this module, I'm quite eager to explore saltcorn-react views!

However, when setting up this module and trying the gettingStartedView, nothing renders on the page and the web-console throws the following errors:

GET https://my.saltcorn.domain/plugins/public/react/main_bundle.js NS_ERROR_CORRUPTED_CONTENT

The resource from “https://my.saltcorn.domain/plugins/public/react/main_bundle.js” was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff).

Loading failed for the <script> with source “https://my.saltcorn.domain/plugins/public/react/main_bundle.js”.

I tried this in unmodified Chromium, as well as Firefox (Librewolf). Also, I tried both storage option configurations for the module and both "development" and "production" build. It also did not work with turning off "Enhanced Tracking Protection" in Firefox.

Saltcorn version: 1.2.0
React Plugin version: 0.1.2
Deployment with docker-compose behind nginx reverse proxy

Could you help me in finding the source of this error?

When you open the plugin cfg menu and you click build, do you get an error?

To debug it, you also can try to set the code source to none, build it, and create a view with the default code.

And can you hit this url
https://my.saltcorn.domain/plugins/public/react/main_bundle.js
with your browser and see if if it returns something
