Failed to load module script

Hello everyone,

I have hosted my Shopify app on a cloud server. It is a PHP template app, but the frontend is not rendering. Instead, I am getting the following error in the console:

Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of “application/octet-stream”. Strict MIME type checking is enforced for module scripts per HTML spec.

When I run the app locally, it works perfectly. However, after deploying it to the cloud server, the frontend does not load.
Has anyone faced a similar issue? Do I need to configure my server differently to serve JavaScript files correctly?

Any help or guidance would be greatly appreciated!
