[object%20HTMLTextAreaElement] on serverconnectform

Hello,

I’ve created a form to be submitted via serverconnectform. The first field is a textarea followed by a number of fields, nothing that has ever broken before.
When the form is submitted, I get a [object%20HTMLTextAreaElement] error in the xhr inspector and when I check the API page called, I see a 404 as it’s trying to fetch [object%20HTMLTextAreaElement] instead of the actual action page (PHP model).

Would anyone have any suggestion on how to track what is wrong? The form is fairly complex and I’d rather not create it from scratch again.

Thanks!
