Redwood UI – "Forbidden" Error While Uploading Attachments on Document of Records (Custom Role)

Summary:

Hi Community,

We have a custom role assigned to HR users that allows them to upload attachments on the Document of Records page. This functionality was working perfectly in the classic UI. However, after switching to Redwood UI, users are encountering the following error when trying to upload documents:

Error: Forbidden

The custom role includes the following privileges:

Manage HR Document Type

Use REST Service – HR Document Types List of Values

Manage Person Documentation

Use REST Service – Document Records

Attached is the screenshot of the error for reference.

Has anyone else experienced this issue post-Redwood transition? Could anyone suggest what additional privileges (if any) are required for this functionality in Redwood UI?
