Dataflow internal error

[robert-murray]

Everything was working fine with my dataflows yesterday. Now I am getting these:

This is from my "top" level dataflow (external entities) which has links from other dataflows. This is the only dataflow that I can still see my entities from and at least get into the editor. But if I try to make any changes I get this:

Something went wrong
Could not perform this operation due to an internal error

This is what I get from a linked dataflow when I try to go into the editor:

Experienced the issue all of a sudden after weeks of successfully completed scheduled refreshesand on-demand refreshes.
In my case, the cause was hidden in the settings / credentials.
Was difficult to spot because the "Data source credentials" section inside settings takes some time to enable.

Dataflows errors all over the place today... Scheduled refreshes in the Service failing which lead to failures in datasets....  Got a bunch of refresh failure notifications in my e-mail inbox, normally 'quiet' on Sundays.... 😞
