What are the exact steps to reproduce this issue?
- Log into a workspace hosted on Baserow Cloud (api.baserow.io).
- Open a specific table (e.g., Table ID: 998446).
- Attempt to apply a ‘Group by’ rule to any column in a Grid View.
- The UI immediately throws a generic “Action not completed” popup.
- Checking the browser DevTools Network tab reveals a hard
500 Internal Server Erroron the POST request tohttps://api.baserow.io/api/database/views/1958379/group_bys/. - Attempting to bypass the view by duplicating the entire table (with or without data) results in another
500 Internal Server Erroron the POST request tohttps://api.baserow.io/api/database/views/table/998446/. - This same 500 error is now happening when trying to group columns on a completely separate table in the same workspace.
It appears the backend database schema/index for these tables has become corrupted or locked on the server side, preventing any structural changes or grouping queries from executing.
