We have no idea when or why AVFoundation is firing this type of error (with a code of AVErrorUnknown). Ironically, once we correct this piece and start returning the underlying error, the clients of WebKit's EME API can start reporting what underlying error they're seeing. And we may be able to write a regression or manual test at that point.
