Crash in 0.35.11: TypeError "'NoneType' object is not iterable" in watched-shows / sync

[Patatra40]

Confirmation

• I have read the README.md on the project homepage
• I have checked if an identical issue or discussion already exists
• I have tried downgrading to find version that can be used as a workaround

The problem

Version

PlexTraktSync 0.35.11
Docker

Problem

Both commands fail:

plextraktsync watched-shows
plextraktsync sync

with:

TypeError: 'NoneType' object is not iterable

The traceback points to:

self.seasons = {}
allCompleted = True

for season in seasons:

inside pytrakt_extensions.py.

Investigation

I verified the following:

• Trakt authentication is valid.
• Plex connection is valid.
• healthcheck passes.
• unmatched works.
• Only watched-shows and sync crash.

I queried Trakt directly from inside the container:

GET /sync/watched/shows

The request returns HTTP 200.

The returned objects do not contain a seasons field, so ShowProgress.__init__() receives:

seasons=None

which causes:

for season in seasons:

to crash.

Temporary workaround

Adding

seasons = seasons or []

before the loop fixes the crash:

self.seasons = {}
seasons = seasons or []
allCompleted = True

for season in seasons:

After this change:

• watched-shows works
• sync completes successfully

Remaining issue

Every show is reported with:

Seasons: 0

so the workaround only prevents the crash.

It looks like the code no longer receives the season data it expects and probably needs additional handling.

ChatGPT helped finding this, I know nothing about coding sorry

Confirming this on 0.35.11 (Docker) as well.

Same exact traceback, down to the line numbers:

File "/app/plextraktsync/pytrakt_extensions.py", line 11, in allwatched
    yield AllShowsProgress(data)
File "/app/plextraktsync/pytrakt_extensions.py", line 114, in __init__
    prog = ShowProgress(**show)
File "/app/plextraktsync/pytrakt_extensions.py", line 94, in __init__
    for season in seasons:
TypeError: 'NoneType' object is not iterable
Error: Error running sync command: 'NoneType' object is not iterable

A couple of notes that might help narrow this down:

• In my run, sync got well into the movies pass with no problems — Adding to Trakt collection and Marking as watched both worked fine for movies. The crash only happens once it moves on to the shows/watched-progress stage, which lines up with your finding that it's specifically the /sync/watched/shows response missing the seasons key.
• Since your workaround (seasons = seasons or []) results in every show reporting Seasons: 0, not just the one that originally triggered the crash, this looks less like a data quirk on one show and more like Trakt's /sync/watched/shows endpoint has changed its response shape entirely (e.g., dropped or restructured the seasons field account-wide, or it's now paginated/nested differently). Might be worth diffing a raw /sync/watched/shows response against the API docs to see if the schema shifted, rather than treating this as a null-check bug alone — otherwise the fix will just suppress the crash without actually restoring watched-episode data.

Will take a stab at PRing this with Claude if helpful!

Trakt has changed how /sync/watched/{type} works: now it requires pagination, and by default it does not provide season info anymore, so one has to explicitly request it with extended=progress.

So the new correct way to do it would be something like: GET /sync/watched/shows?page=1&limit=250&extended=progress.

See here for more info: trakt/trakt-api#775

Probably needs to be fixed upstream in pytrakt? glensc/python-pytrakt#103

Same issue here since yesterday around 8pm UTC. Commenting to follow for any updates.

Same :/

Confirmed on Windows 11 using PlexTraktSync 0.35.11.

Python: 3.13.8
Plex Server: 1.43.2.10687

I can reproduce this with:

• plextraktsync sync
• plextraktsync watched-shows
• plextraktsync healthcheck

I also verified the raw response from GET /sync/watched/shows using Invoke-WebRequest. It returns valid JSON but does not include a seasons array by default, which matches the discussion above.

The watch command still connects to Plex and continues running.

I can confirm I'm receiving same error on latest release.

I'm using the file in the commit seen in this thread, above, and it works. It looks like a significant update and they may be putting some finishing touches on it. Thank you to the contributors!

Fixed with 0.35.12
