The error went away after a retry (because requests cached?), but worth researching what happened.

Maybe you have the same movie in differents libraries.
I know how to fix this.

[glensc]

Yes, very likely, I have "Movies" and "Movies (Archive)" libraries, so I do move the files around.

I wonder what is the expected behavior in such situation.

Example : in your trakt watchlist at rank 2 you have The Mask movie.
And you have The Mask in 720p in Plex library Kids, The Mask 1080p in library Movies and The Mask 3D in library 3D Movies. All are the same movie from 1994 so have the same id.

If you sync all those libraries, which version of the movie do you expect to be added in the Plex playlist "Trakt watchlist" ?

I would say the first found, so if libraries are sync alphabetically, it would be the 3D version. 😄
If you add the 3 versions, it would mess up the list and ranks.
