Issue with Power BI Dataflows Gen 1 Using Dremio Software Connector

Description:
We are using a self-deployed Dremio OSS instance to feed Power BI datasets, semantic models, and dataflows via the Dremio Software Connector.

Context:

  • Dremio OSS powers Power BI datasets and semantic models.
  • All existing Power BI dataflows and datasets refresh successfully without requiring a Microsoft Data Gateway.
  • The Dremio connection status in Power BI’s “Manage Connections and Gateways” is marked as Online.

Problem:
Since mid-October, I have been unable to create new Dataflows Gen 1 without using a Microsoft Data Gateway. However, existing dataflows and datasets continue to function as expected without the need for a gateway.

Questions:

  1. Have there been any recent changes to the Dremio Software Connector that now require a Data Gateway for Dataflows Gen 1?
  2. Is it possible to access older versions of the Dremio OSS documentation for reference, I would like to check what the documentation said about data gateways in previous versions such as Dremio 24.2.X?

I appreciate any insights or guidance on resolving this issue.

@balaji.ramaswamy sorry to bother you, but I do have some urgency on this matter. :pray:
