Stacktrace throwing a 500 error

[davidbhoward]

I ran into this error tonight. I think what triggered it was in Plex a user started some downloads of content on their device since they are traveling. That is only my best guess here.

Puma caught this error: labels must have the same signature (keys given: [:user_id, :user] vs. keys expected: [:user_id, :username] (Prometheus::Client::LabelSetValidator::InvalidLabelSetError)
