What are the "missing input parameters" when a document creation is not successful?

I am creating a document by Employee ID.

Our Manager Selection Method is Position Reports_To.

Eval. start date = 1/1/2022 & end date = 12/31/2022.

For few employees, when I create the documents, the EPMGRDOC completes successfully, and when I view the results, I see the message "The document could not be created as input parameters are missing or invalid. Please contact your system administrator."

The position is active, and the reports_to is active. Both incumbents have hire dates more than 5 years ago.

Using the same evaluation type and template ID for other employees work.

The system doesn't give any indication to which parameter is wrong. The App Engine also just
