Dev environment is flawless. Production doesn't work

I ran into a similar problem in my development process, which I documented in detail here: [Video Summary App] Follow my journey building a webapp as a non-coder - #7 by robinbobinpopin

Without knowing what you run into, I suspect it’s an API issue. My specific problem is that the API I was using was meant for ‘private use’: when I used it locally or during dev server, it works fine. As soon as it was deployed on a public server, YouTube blocks the API.

If that sounds like the issue you have, here are my suggestions:

  1. Look into alternative API (you may have to pay for it)
  2. Package the app to be running locally

Hope this helps you.
