    Hi S_Grasberger ,

    Thank you for reaching out to the Microsoft Community Forum.

     

    In Fabric, go to Data Factory --> Dataflows Gen2 and create a new Snowflake connection with Key Pair. Recreate your queries in the new Gen2 dataflow and validate refresh.

     

    I hope this information helps. Please do let us know if you have any further queries.

     

    Regards,

    Dinesh

Hi
I've got the same problem, except I am creating a gen 1 dataflow from scratch (no gateway). I've tried completely deleting everything snowflake related (gateway connection and the dataflows) and starting again and I still get the same error. The microsoft page I had open is now giving a gateway error, so I'm not sure what's going on with it - https://blog.fabric.microsoft.com/en-nz/blog/snowflake-key-pair-authentication-generally-available?ft=09-2025:date


If anyone manages to resolve this, I'd appreciate some help!
