Dataset Materialization fails, sigma-support org, CSV source.
Error: Failure - No active warehouse selected in the current session. Select an active warehouse with the ‘use warehouse’ command.

One dataset fails to materialize completely, several others showed the same error message, but eventually materialized on their own (not sure how).

Hey Yuri!

We see this error when a warehouse is not selected for write-back from Sigma! If you are an admin you will need to go into the connection settings and make sure to assign a write-back destination!
