Getting blank screen after clicking install

[mahamudml]

I have server side subscription on home page once homepage is loaded.
In production I'm getting blank screen after clicking on install and following error message, it is still on SHOPIFY_APP_URL domain.

Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/html". Strict MIME type checking is enforced for module scripts per HTML spec.

The app is installed, after going through admin>apps>My App it works fine

I'm down with a viral fever so gonna be a little while before I can debug this, but can you please attach screenshots / screen records / snippets so I can take a look?

After googling the issue I think it is because .js is missing while import

I tried in new ingonito tab and it is working now :|
