Whatever I do I just get 500 error from Apple Music API

[neoromantic]

I've successfully created a token, but any request just ends with 500. For example:

Does anyone has an idea on what should I try? Googling pointed out people with the same problem, but no solution.

Same here with freshly generated tokens.
