Column ".name" cannot be resolved

Hello team, I hope you are well!

I have used Metabase filters in the past and worked fine.

However, I am facing this issue here, that although everything is referenced properly and variables have been specified and mapped to the appropriate data source filters and the data types are correct , I get this error message whatsoever.

As this logic has been successful in previous use cases (yet other data sources within the same DB) as I mentioned above, could it be some issue related to the datasource itself- say some permission issue for example ?

Any help would be much appreciated.



Troubleshooting info?
