Materialization failed

When attempting to materialize a dataset I see the following on the Materialization page/tab:

Failure - No active warehouse selected in the current session. Select an active warehouse with the ‘use warehouse’ command.

Any idea what this means?

Hey Darien!

Can you check your connection settings for your warehouse? We often see this error coming up when there is no Materialization Warehouse selected for a user!

A separate warehouse for materialization is not a requirement. However if one has been specified then we need to ensure that the Sigma system user has the correct grants to write to it.
