Internal server error

I just noticed that using GetUserIdFromNameAsync from a local script gives this strange error. And idea why this is happening?

Make sure to wrap Async calls in pcall, just like you do with datastore requests etc, because these calls may fail due to network errors or temporary unavailability of resources.

I’m also not entirely sure if this method is supposed to be usable on the client, I’ve never used it that way before.

It’s wrapped in a pcall, was just testing why it didn’t do anything.
I’ve been using this for quite a while and it has always worked before.
