That is really strange, i can’t really recreate this issue, or similar ones you reported.
Is this happening to all the queries or with this specific one? Is this happening with simpler queries, or only with ones with joins? Is it happening to changes like this specific one or any other change?
Please recreate the issue with the debug on and attach the debug log here.
Looking at your similar issues, it could be your Wappler installation is somehow corrupted, so maybe you can try a clean install Reinstall Wappler from scratch
