markPlayed and markUnplayed Error for medias from Plex Discover

[simonc56]

Describe the Bug

Plex Discover allows to get Movies and Shows that user don't have in PMS library.
Problem : the markPlayed() and markUnplayed() functions do not work for those medias found with discover.provider.plex.tv it raises a plexapi.exceptions.NotFound.

Movies and Shows (found from Plex Discover) watched status can be switched with Plex Client, we shoud be able to do it through Plex API too.

Code Snippets

>>> myMovie
<Movie:nan:Cairo-Conspiracy>
>>> myMovie.markPlayed()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\me\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\site-packages\plexapi\mixins.py", line 274, in markPlayed
    self._server.query(key, params=params)
  File "C:\Users\me\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\site-packages\plexapi\server.py", line 705, in query
    raise NotFound(message)
plexapi.exceptions.NotFound: (404) not_found; https://metadata.provider.plex.tv/:/scrobble?key=nan&identifier=com.plexapp.plugins.library <Error error="Not Found" message="Not Found" statusCode="404"/>

Expected Behavior

No error raised.
Just like items from user's PMS library.

Additional Context

Requests to switch watched state of items from Plex Discover are :

https://discover.provider.plex.tv/actions/scrobble
https://discover.provider.plex.tv/actions/unscrobble

with data:

key=(ratingKey)
X-Plex-Token=(accessToken)
...

And we can check viewCount and lastViewdAt with request :
https://metadata.provider.plex.tv/library/metadata/(ratingKey)/userState

I think this uses the same Plex cloud database (linked to user account) to sync PMS watched state and ratings.

Using Plex Discover to mark items as played/unplayed is a clever way to do this. +1 for this issue

[glensc]

Started something:

• Add support Discover isPlayed/markPlayed/markUnplayed #1090

If you could test, would be awesome

@twolaw I think you should just use these methods in your project directly:

• python-plexapi/plexapi/myplex.py

  Lines 940 to 959 in 8652bee

  	def isPlayed(self, item):
  	""" Returns True if this item is played. """
  	userState = self.userState(item)
  	return bool(userState.viewCount > 0) if userState.viewCount else False
  	def markPlayed(self, item):
  	""" Mark the Plex object as played. """
  	key = f'{self.METADATA}/actions/scrobble'
  	ratingKey = item.guid.rsplit('/', 1)[-1]
  	params = {'key': ratingKey, 'identifier': 'com.plexapp.plugins.library'}
  	self.query(key, params=params)
  	return self
  	def markUnplayed(self, item):
  	""" Mark the Plex object as unplayed. """
  	key = f'{self.METADATA}/actions/unscrobble'
  	ratingKey = item.guid.rsplit('/', 1)[-1]
  	params = {'key': ratingKey, 'identifier': 'com.plexapp.plugins.library'}
  	self.query(key, params=params)
  	return self

later if #1090 gets merged can use the PlexApi methods.
