REST API error in DOR redwood page

We are receiving following error message when Employee opens "Documents of Records" self-service page.

Error: You don't have access to this worker's assignment info. (PER-1532312)

Upon inspection - we can see following REST API call is failing with 400 (Bad Request) status. But there is no REST Service privilege matching this API name. Has anyone else faced this issue ? What is the privilege added to resolve this issue in DOR pages ?
