Dataflow error: Challenge Error Data source credentials are missing or

[AnthonyGenovese]

I am getting the following error when trying to load data into a lakehouse using a dataflow. 
"Challenge Error Data source credentials are missing or invalid. Please update the connection credentials in settings, and try again."

It loads data correctly into staging as the first step. Then the second step runs for 6 hours, finally throwing the above error.  Total rowcount for these loads are <10k records. Tried refreshing the credentials in the dataflow and in the settings, no luck.  I do see these tables in an "Unidentified" folder in the lakehouse. (See third picture)

I'm getting the same error. Everything was working fine on Friday, nothing has changed since, and now all my Dataflows give this same exact error. Help!

the issue that you might be encountering might be unrelated to the topic at hand. I'd recommend reaching out the support team by raising a ticket.

Issue is now resolved when using the latest gateway server. (As of writing July 2023)

Were things working fine with you before? Or were you having other issues as well. I was still having issues when this surfaced.
