Title: Correct warehouse value for the Iceberg REST Catalog endpoint on a trial project

Hi all,

I’m evaluating Dremio Cloud for connecting a third-party data-governance tool to Open Catalog via the Iceberg REST Catalog protocol (https://catalog.dremio.cloud/api/iceberg), following the pattern in the “Connect to External Engines” docs (the Apache Spark example).

I’ve got OAuth2 token exchange working fine (PAT → access token via login.dremio.cloud/oauth/token, grant_type=urn:ietf:params:oauth:grant-type:token-exchange), and I can reach /v1/config — but I can’t figure out the correct warehouse parameter value:

  • warehouse=<project-name> (first-project) → 401 Unauthorized
  • warehouse=<project-id> (a UUID) → 404 Not Found: Unable to find warehouse <uuid>

The docs say “the default catalog in each project has the same name as the project,” but that doesn’t seem to be working for me. I couldn’t find the value anywhere in the console UI either (no dedicated “Catalog” page visible in my trial tier, and SHOW CATALOGS / SHOW NAMESPACES in SQL Runner didn’t surface it).

Is there somewhere in the UI this is displayed, or a different value I should be trying? Happy to share more details if useful.

Thanks!
