What's the response code that you get back from the server for this issue @evilarceus ? Would it result in a 500? (As I mentioned in response to another issue here) I'm experiencing intermittent 500s from the public server.

The status code should be 500 for this issue. If you're getting random status code 500s, it's most likely because of this issue.

i'm also getting intermittent 500s on the artistInfo endpoint

That's a playlist

annadnl commented 4 years ago

it is not, it's armin van buuren :-)

spotify:artist:0SfsnGyD8FpIN4U4WCkBZ5

but you are correct, if you search for "0SfsnGyD8FpIN4U4WCkBZ5" on the platform it does return a playlist. could this be a hint towards where the problem comes from? that a playlist and an artist have the same handle?

Stoley commented 4 years ago

ah you're right, never seen that before
