Can you give me your Python version as well as the websocket-client version ? Thank you.

[Metuant]

Python 3.8.13 Name: websocket-client Version: 1.3.2 Summary: WebSocket client for Python with low level API options Home-page: https://github.com/websocket-client/websocket-client.git Author: liris Author-email: liris.pp@gmail.com License: Apache-2.0 Location: /usr/local/lib/python3.8/site-packages

To clarify - running PAL in docker.

@RemiRigal was this info helpful? I continue to see this periodically in the logs.

P.S. This tool is amazing - really appreciate your work!

[RemiRigal]

Hi @Metuant, I've tried to reproduce the issue but since you are using docker it's unlikely that it's coming from Python or its packages. It looks like the websocket is not receiving messages properly so I'm leaning toward a network issue or a Plex issue. Are you running an oudated version of Plex ? Anyway, I think that this is related to the other issue you opened (#49).

P.S. This tool is amazing - really appreciate your work!

Thank you, I really appreciate it :)

[Metuant]

Sorry for delay in response - i'm running plex 1.27.2.5929 - any other things I should review to help troubleshoot?

[Metuant]

@RemiRigal - I think i figured this out. It seems PAL produces this error on Audiobook titles. Is it possible to enhance the configuration file with a library exceptions list?

[Metuant]

@RemiRigal - bumping this. I think an exclusion list would resolve this message as it seems localized only to Music library

[RemiRigal]

@Metuant The issue is that the exception occurs within the websocket-client package, not in PAL. The WebSocketPayloadException raised means that either the websocket frames are corrupted (see issue https://github.com/websocket-client/websocket-client/issues/216) or the websocket frames contains non-utf8 characters (see snippet).

If the issue comes from corrupted frames I can't do anything in PAL that can solve this, it needs valid frames in order to filter out messages. By the way, PAL will ignore any media that is not a TV Show episode so the exclusion list is there already.

However, if it's an encoding issue, I can disable utf8 validation in the websocket connection. By any chance, do you have any audiobook with non-utf8 characters in them ? (Title, author, etc...)

[Metuant]

@RemiRigal Oh, interesting! Thank you for providing clarity, I think we're on to it. Re: Audiobooks with non-utf8 characters, yes, many.

Further log data that contains some titles in question:

However, if PAL ignores any media that is not a TV Show, these should be ignored as they are scanned in as "Music" not "TV Show" - correct?

[RemiRigal]

However, if PAL ignores any media that is not a TV Show, these should be ignored as they are scanned in as "Music" not "TV Show" - correct?

PAL cannot chose the messages sent by the Plex server, it instead filters out the messages that are not related to TV Shows. But in order to do that the message must be decoded first, and the error you are getting is happening at an earlier stage.

Can you try the newest version available (remirigal/plex-auto-languages:master docker image) and let me know if you are still getting this error ?

Error with must recent pull - I think we'll solve both my open issues if this gets closed.

[RemiRigal]

We are getting there !

Can you try the latest version ?

[Metuant]

Indeed we are! ^_^

Latest pull looks pretty clean. Only thing I see are the following...are they related?

[RemiRigal]

Sorry for the delay, can you try the latest version ? The decoding errors should now be silent.

[Metuant]

All good - yes, messages are silent in recent pull.

Ty!
