Inplace post edits are returning Fault 404: 'Invalid attachment ID.'

I am trying to use your library (v2.1) to write a script to replace broken links after a blog migration to Wordpress.com. After retrieving posts and making corrections to the post.body, I

if not(wp.call(EditPost(post.id, post))):
    logging.error("Unable to edit post %s" % (post.id))
else:
    logging.info("Successfully updated post %s" % (post.id))

Running this consistently yields this error, irrespective of the post in question or whether any changes were made:

Traceback (most recent call last):
  File "wplinkrepair.py", line 260, in <module>
    fix_errors=args.repair)

  File "C:\Python27\lib\xmlrpclib.py", line 793, in close
    raise Fault(**self._stack[0]) 
xmlrpclib.Fault: <Fault 404: 'Invalid attachment ID.'>```

Any suggestions?

just running into the same issue and the solution:

post.thumbnail = post.thumbnail[‘attachment_id’] before EditPost

did in fact fix the problem for me - Thanks!

WordPress gives more information in GetPost than it expects in EditPost, which is leading to this issue. I can handle it better in the library, and I’ll try to do so in the next release.

In the meantime, you can try calling post.thumbnail = post.thumbnail['attachment_id'] before EditPost. This will change it to the value expected by WordPress. Let me know if that doesn’t work and I can dig deeper.
