We got this error in a forms save to repository task that saves an uploaded document.
One or more required fields were omitted or had a blank value. [9066]
In the past this would just wait for your to fix the issue and retry the task. Now in version 10.4 (10.4.2.665) it saves the document anyways and continues to save another copy every few weeks. We have 11 copies of the uploaded document saved all without the template being assigned. All saved by Forms.
I will work with them on resolving the field issue, but why all the copies of the document?
