metadata agent
I'm writing a custom metadata agent to pull metadata about movies from a new site.  
  
I copied an existing module and rewrote the "search" and "update" functions. The search seems to be working- I can resolve movies against the site's search feature, and it is replacing the title of the movie in my library to match the site. The update function is working according to the logs, but I don't get the metadata updated in my library.   
  
Looking into the issue further, I see the following error in my Plugin's Log:  
  

```auto

<br />
2013-01-12 14:53:50,849 (-4faed000) : DEBUG (model:32) - Loading model with GUID com.plexapp.agents.<my package name>://<a metadata id><br />
2013-01-12 14:53:50,850 (-4faed000) : ERROR (model:194) - Cannot read model from /Users/<my user name>/Library/Application Support/Plex Media Server/Metadata/Movies/b/f4a4a40fed05f<br />
835e1a112b0f8799d7b0e170b9.bundle/Contents/com.plexapp.agents.<my package><br />

```

  
  
Has anyone else encountered this issue?

I think I’ve made some progress-  
  
  
  
I’m no longer getting that error. The log now indicates that the data is serializing to the file:

```auto

```

  
  
And when I view that xml document I see the updated summary and other attributes. However this summary still does not display on my plex library web view or plex client.
