json.decoder.JSONDecodeError with Deezer API

🎈 Using Streamlit
1

Hey!

I’m using the Deezer API on one of my app’s pages, and while it worked well until recently, I’m now getting the following error message:

json.decoder.JSONDecodeError: This app has encountered an error. The original error message is redacted to prevent data leaks. Full error details have been recorded in the logs (if you're on Streamlit Cloud, click on 'Manage app' in the lower right of your app).

Traceback:

Here’s the link to my app.
And here’s the link to my repo.

I tried updating Streamlit via my requirements.txt, but it didn’t solve anything so I ended up removing the versions to have a more generic requirements file… It didn’t change anything either.

Any ideas on where this issue might come from?

It looks like request.text is not valid JSON. I don’t think messing with your requirements is going to fix that.

The original error message may contain useful details, but you didn’t tell us…

Here is the original error message:

Well, nor really helpful by itself after all. Yet it makes it clear that request.text is not JSON.
