Serialization ERROR

Dev Community Dev/API Corner
1

I am receiving a serialization error when plex is trying to serialize some of the tv_show objects during my scan and metadata retrieval using custom scanner and agent.  can anyone think of why or what could cause a serialization issue?

 

could it be the way i am setting metadata

could it be special characters in the metadata itself

a bug with standard plex py scripts?

 

The error is random and occurs for about 10 - 15% of my items

 

There are actually 2 errors listed in the code below.  1 in search and then 1 in the serialization.  the search error has been going on for a while for me, and i can't fix that one, but the serialization is new.

nobody has any ideas on this serialization issue?

I just wanted to close this thread out.  I figured out what was going on and wanted to share for anyone else having this issue.

Issue:

1) receiving errors on update and errors on search indicating that there were the wrong number of args being passed in.

1 Solution) I noticed that there were 2 classes defined in the same exact file which was most likely due to mutliple people working on the same code.  Removing this redundant definition of the same class solved this error

2) Serialiaztion Error when plex was done retrieving metadata for the current item.

2 solution) This was actually being caused by the what I was passing to the plexthememusic agent.  When I added in the code to set the metadata.id so that plexthememusic could contribute to my code I DID NOT check for the existence of the ID in my source before setting it.  What happens then is the agent code tries to serialize the object in order to pass it to the thememusic agent.  when trying to serialize the metadata.id that is not a string or unicode (in my case blank or null) it throws a serialization error and ultimately prohibits ANY metadata from being added to the current item.
