Dataflow refresh error - culture is not supported

[GuillaumeB_RSM]

Hi all,

I have a Power BI Dataflow retrieving data from an API.

Among its table/columns, it is returning date values formatted as english dates. Since last night, the scheduled/On demand refreshs fail because of this error : DataFormat.Error: The specified culture is not supported. <ccon>en-EN</ccon>

I haven't made any recent changes to this dataflow. And there is no error showing in the preview/when saving the dataflow (even when using keep errors on all columns), only the refresh fails.

I have tried to follow this previous topic : https://community.fabric.microsoft.com/t5/Desktop/Error-The-specified-culture-is-not-supported/m-p/8...

but I can't find the "local setting" on Power VI Service...

Can you help me ?

Thanks,

Guillaume

Same issue here. The PowerPlatform.Dataflows([) Connector fails at the first step:

I think I've managed to solve it on my end. I had to go into each dataflow, click options, click regional settings and then pick English (United Kingdom). Save and close, refresh.

Good grief 😫 
But thanks!

I've found a solution,

It seems that the "en-EN" culture has been decommissioned for M date functions, so I've switched all my formulas to "en-US" on my dataflow.

It now refreshes successfully

Unfortunately, some of my dataflows are failing which don't even contain date fields.....

Same issue. Most of my dataflows are failing since Sunday night (UK time)
