Hi,
PowerApps Portals Web Form is displaying an error, see below:

I have enabled SharePoint integration from Dynamics 365 admin center and ticked the entities that I want to be sent to SharePoint.
In PowerApps Forms I've create a subgrid and set the table to "Document Locations (Regarding)" and the default view to "Active Document Locations".

I've tried reconnecting SharePoint integration, but the error still remains the same. Does anyone have any ideas?
