Power BI Desktop - Dataflow - The name 'Lakehouse.Contents' does not exist in the current context.

Hi everyone, I'm encountering the following error when trying to connect to a Dataflow using the Dataflow connector in Power BI: The name 'Lakehouse.Contents' does not exist in the current context...

Hi vikramkumawat ,

This error means the Lakehouse.Contents connector is either missing or not recognized in your current Power BI or Fabric environment. This often happens due to either recent service changes or outages in Microsoft Fabric or Updates or breaking changes to the connector or permissions or Attempting to use a Fabric-only function in classic Power BI Desktop or unsupported environments.

To fix the issue you can start by Checking the Fabric Service Health by going to the Power BI/Fabric Support page to see if there are any ongoing incidents affecting Lakehouse or Dataflows. Then update Power BI Desktop as connector support is updated frequently. Validate Permissions: Double-check that your user account still has access to the Lakehouse and Dataflows in Fabric. Restart and Reconnect: Close and reopen Power BI/Desktop, and try reconnecting to the Dataflows. Microsoft Community & Docs: Fabric documentation on Lakehouse connector

Hi rohit1991 ,

Thank You so much for your response, Yes I tried the refresh in a different system with PBI Desktop June 2025 version in that it refreshed without any error. but in my system it is July version. I am not sure if it can be possible that it is happing due to the update or anything else is happning, because to refresh I used same creds and same network, just the difference was PBI Desktop version. 
If the issue is with version only then is it possible to install older versions of PBI Desktop ?

Thanks.

    Hi vikramkumawat ,

     

    It definitely sounds like this issue is related to the July 2025 Power BI Desktop update, especially since the same dataflow refresh works perfectly on the June version with identical credentials and environment.

     

    Yes, you can install an older version of Power BI Desktop:

    1. Uninstall your current version first.

    2. Download and install the June 2025 (or any previous) version from the official Power BI Desktop archive.
