YouTube iframe API - "unknown" player quality

[aaronleopold]

When I build this application, the onPlayerReady event does not fire on some videos. If you try and play/pause the video, the onError will of course trigger since the player was not loaded, however the error event has the following debug information in seemingly most instances of this occurring:

"{ \"debug_playbackQuality\": \"unknown\" }"

Running the app in development, I see that for the same video I get current quality: – "unknown" without error (i.e. the player successfully loads and plays the video audio).

suggestedQuality field in the loadPlaylist argument object is deprecated, and you cannot specify quality when creating the player. Because of all this combined with the fact that it only occurs in production environments, I am currently unsure of how to correct this.
