Help with Semantic Model connection

[GlibAvrutin]

Hello guys, I'm new to the PowerBi service so please don't judge too harshly  🙂

The thing is that I've updated some kql RLS stuff in my dev fabric workspace and now trying to refresh the semantic model in the same workspace, but it fails because it points to the different kql database (not in my current dev workspace, error message attached). I've tried changing cloud connection but it didn't work, asked AI and searched some topics on this forum and couldn't find any good pieces of info. 

Data source error: Bad request: Semantic error: Error in row_level_security query for database("fba6f93a-
102c-4b5d-88d5-5043df92810d").table("_MV_DimResponse"): the following operators were blocked:
'summarize' (only the following operators are allowed: 'as', 'distinct', 'extend', 'join', 'limit', 'project', 'project-
away', 'project-keep', 'project-rename', 'project-reorder', 'union', 'where'). Error = Semantic error: Error in

Thank you very much in advance for any help!

Hi @Mauro89, Thank you for your answer. Yes there were issues with KQL query in all of my fabric workspaces (dev, staging and prod) and I managed to solve them for dev database, but the semantic model located in dev workspace, which was created and configured not by me, points to the db in prod workspace, not in dev, as the id in the error message suggests.

If you just solved the issues in DEV workspace/database, then maybe the KQL code differs between DEV and PROD. And as the semantic model takes the PROD KQL DB maybe this could be worth checking and comparing. 
I also found this interesting post which might help if there are issues with related tables https://stackoverflow.com/questions/67092083/how-to-recover-from-a-broken-row-level-security-policy#...'

Best regards!

Yep, that's right, and basically the question is how to make semantic model point to the dev database instead of prod. I tried creating new cloud connection in the model parameters tab,  but it didn't give any results (screen attached) 

Thank you for support

Hi @GlibAvrutin,

welcome to Power BI and the community 🙂 and no worries, the community is here to help, not to judge  😊

So your error message indicates some trubble with the KQL query which is underlying in your KQL database. Seems like you have some semantic issues as the error states the "summarize" operator is not stated correct.

Therefore it would be a good first point to start investigate the KQL query. If you can, share the query with the community then we can dive deeper. 

Best regards!
