I'm trying to use deploy to keep content on a dev site current with the content that's still being added to the current live site during an upgrade. I have everything set up, and the communication is working fine, but the first node fails because of an "An illegal choice has been detected. Please contact the site administrator." Looking at my watchdog error, the error is

Illegal choice 0 in Teaser image size element.

This is a field added by the pp_img_extract module via hook_form_alter() on the node edit form. In looking at the code, the value in the field (a select list) is valid in both locations. Unfortunately, this error is on the first node and makes the entire deployment plan fail. Any suggestions on how I can fix this so I can deploy my content?

Thanks.
