Datamart Internal Error 500 when using dataflow

[kblackburn]

Using dataflow as a source in datamart and getting repeated errors on "wrapping up". Have tried both dataflow connectors and same issue.  Please help!

Hi @kblackburn 

Can your dataflow work normally ? At which step did you get this error?

Hi @v-yetao1-msft thank you for your reply.  Yes, my flow is working perfectly normal. I can bring the data in via the flow connector. The error occurs during the "wrapping up" stage -see below:

I'm getting a similar error when I use dataflows to load a Datamart.

My issues was related to this. Once I disconnected from Gen2 storage, everything worked fine.

• Datamarts aren't available in workspaces that are bound to an Azure Data Lake Gen2 storage account

Best of luck!

My understanding is all workspaces default to Azure Data Lake Gen2 for underlying dataflow outputs; how'd you disconnect?

Is there a workaround that allows Power BI dataflows to load into a datamart (without hitting this error)?
