Dataflow refresh started failing today MashupException.Error

Hi!   I've had about 90 dataflows set up for a few months now. Last night all but 2 of them failed with error MashupException.Error The two that succeeded were very small tables with less than 100...

pqian_MSFT What happens now, all the previous errors do not occur because I am now stopped in the 'Choose destination target' dialog with the following error:

 

To be clear: 

0__create DF

1__connect to on-prem source (data comes in, can see table)

2__disable staging on the query

3__in Data destination, click + icon and select Lakehouse

4__in 'Choose destination target' dialog, select the lakehouse and click next (validation ensues for a couple of minutes)

5__error message above.

 

Do you still want me to proceed with getting the GW Mashup logs or is this enough info to start a different exploratory path?

Yes please, turn on GW logging is critical to see the real issue. Also, for this particular error, the correlation is a "session ID" from the Options -> Diagnostics dialog.
