connection to dataflows
I am unable to connect to Dataflows in PBI desktop. Worked fine yesterday, looks like an updated version has installed itself and today I can no longer connect. The app environment is still working. My desktop version is - Version: 2.145.1105.0 64-bit (July 2025)
On refresh I can this message for each data source
"The import PowerPlatform.Dataflows matches no exports. Did you miss a module reference?"
In Power Query I get this message
"Expression.Error: The name 'PowerPlatform.Dataflows' wasn't recognized. Make sure it's spelled correctly."
When I click on Get data - Dataflows, nothing happens.
Any help would be appreciated.
Yes, Microsoft fixed the bug so the most recent version should be safe 🙂

Go into the Power Query editor and change the source connection string from
= PowerPlatform.Dataflows(null) to = PowerBI.Dataflows(null)
This would require you redoing all subsequent Applied Steps starting from the NavigationThat's what I got from copilot too, but in practice it doesn't work, perhaps because I'm using gen2 dataflows.
UnsupportedOperationForClientException: The operation is unsupported. Please try updating the client version.

I think I'm going to have a heart attack. It will take me weeks to move all my dataflows and update all my PBIX files.
Someone in Microsoft should get fired. This is ridiculous 🤬This is a BUG 🎯
When can we expect a fix from Microsoft? Anybody knows how fast they are in fixing their own failures?
same here, the same version, was working a while ago
Same here ! all of my semantic models are corrupted !
Needed to replace in M code the connector PowerPlatforms.Dataflows() by PowerBI.Dataflows()you could have downloaded PBI May version, it still works there
I experience the same issue. reinstalled an older version of PowerBI for the time being until it gets fixed.
I have installed May version on top without uninstalling the previous one. Did not fix the problem.
I first uninstalled my current version (july one) and then installed this one: 2.144.878.0 64-bit (june 2025). For me this one worked.
I have created a lakehouse and then published allthe dataflows into the lakehouse, then changed all my M codes in advance editor to point the PBI report to the lakehouse to get all the data tables. It has worked, just taken a few hours for one report. A few more reports still to do.
This morning I downloaded a Power BI report that needed adjusment, and whenm I opened Power QUery, all the tables that had a "PowerPlatform.Dataflows" connection were broken. When I tried to connect a new dataflow source, the only option now was "Legacy". Microsoft apparently discountinued this connection type =( I report using tyhe "PowerBI.Dataflows" source.

Hi ROgle85,
Thanks for reaching out to Microsoft Fabric Community.
Looks like the issue was because of temporary bug that affected the visibility of the Dataflows connector. The connector is now available again in power bi desktop and should be functioning as expected.
I request you to please check once and let us know if the issue persists and let us know if you need any further assistance.
Thanks and regards,
Anjan Kumar Chippa
