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:
- Look into alternative API (you may have to pay for it)
- Package the app to be running locally
Hope this helps you.
