Benign error in nc log - Cannot set response code - headers already sent about music HOT 5 OPEN

Now I managed to reproduce and fix this. The key was to use PHP 8.3, this error didn't appear with PHP 8.2 regardless of the cloud version.

Thank you! I just tested the fix on my install and its working fine (Isn't PHP a neat thing?). Guess just to go show how much I use the app that it was triggered by every new song I listened to :)

Thanks for the report. What is the logging level where this is shown? I haven't seen this on NC 28.0.2 but maybe there is some new check in 28.0.3. It's possible that I'm using the NC ICallbackResponse API a bit incorrectly in a way which doesn't cause any actual problem.

It shows up at the error level.
