EntityMetadataWrapperException: Invalid data value given. Be sure it matches the required data type and format. in EntityDrupalW

I've been able to use restws to do a get, and a post, but not a put (an update).

I get this error:
EntityMetadataWrapperException: Invalid data value given. Be sure it matches the required data type and format. in EntityDrupalWrapper->set() (line 744 of /Users/barnettech/Sites/belldev/git/dev/babsoncomm/docroot/sites/all/modules/contrib/entity/includes/entity.wrapper.inc).

I looked through the issue que and saw the other 2 issues that were like this one. I applied the patch, but it didn't fix the problem.

// uid.

$result = update_user($uid);

I'm getting the following watchdog error:
Location: http://bell7:8888/user/22.json
Message: EntityMetadataWrapperException: Invalid data value given. Be sure it matches the required data type and format. in EntityDrupalWrapper->set() (line 744 of /Users/barnettech/Sites/belldev/git/dev/babsoncomm/docroot/sites/all/modules/contrib/entity/includes/entity.wrapper.inc)

I tried applying patch http://drupal.org/node/1956752 but this did not help. I've been tracing through the code, but I'm still unable to figure out exactly what the issue is.
