403141: Forbidden 'server administrator' isn't authorized to update the datasource.

Describe the bug
I am using a server administrator account to perform all these updates/moving. However, I am unable to move data sources programmatically from one project to another project within the same site. But I am able to move workbooks.

Versions
Environment Details, including:

• Tableau Server version: 2021.1.17
• Python version: 3.9.7

• On-prem Tableau Server

To Reproduce

with server.auth.sign_in(tableau_auth):
    #move workbook
    move_workbook = server.workbooks.get_by_id(workbook_id)
    move_workbook.project_id = target_project_id
    target_workbook = server.workbooks.update(move_workbook)
    
    #move datasource
    move_datasource = server.datasources.get_by_id(datasource_id)
    move_datasource.project_id = target_project_id
    target_datasource = server.datasources.update(move_datasource)
