Hi @jose_henrique ,

I had exactly the same problem. I had the impression that the problem was linked to an overconsumption of resources on my Fabric capacity.
However, several of us had this problem at approximately the same time, which makes me think it was more of an internal platform problem. Normally, things should have returned to normal a few minutes after the error message. Is this the case?

I'm having the same error also every time I try to refresh a dataflow gen 2.

In some cases it gets back to normal, but i have multiple dataflows and only 1 per an hour and a half can run without errors, and with this scenario it becomes impossible to work, now i'll wait until it gets fixed or at least with less erros than today
