I have a HTPC instance that never sleeps/hibernates/etc. On rare occurances when playing a file I get the Playback Error [existsorThrow] Value is undefined or null! error.

Logging to the server I see the following entries:

[Req#2515bad] [Plex HTPC for Windows] [redacted] Failed to create and set current playable media item - [existsOrThrow] Value is undefined or null!
[Req#2515bad] [Plex HTPC for Windows] [redacted] [PlaybackSessionController] we failed to create a playable URL!
[Req#2515bad] [Plex HTPC for Windows] [redacted] Playback error occurred. Reason: FailedToCreatePlayable, Failed to create a playable with the current play queue item! Message: [existsOrThrow] Value is undefined or null!

I can play other media from the same library but even after playing another item the item throwing the error will not play. If I reload the software I can play the media throwing the error with no problem.

This problem has been ongoing for a long time. It has persisted across multiple server and client versions. It is random and I know of no way to trigger it at will except that once happening it will not resolve till the software is closed and reloaded.
