Error message: DataflowInternalError

[Anonymous]

On refreshing or connecting to a dataflow in Power BI service we get the following error message:

The dataflow contains data from an Azure Gen2 data lake.

Until yesterday all worked fine.

Someone any clue what happened?

Thanks in advance,

We have been able to solve this.

What we did: We created a new dataflow on the same data lake that caused the error.
We got an error message saying something wrong with one of the attributes in one of the tables.
After solving this issue all worked fine again
