Trying out Auto ML with a regression analysis. When training the model, getting this refresh error-message:
Tried it with 2 dataflows, both the same.
This could be related to a query which imposes undue memory pressure. You may try Optimization guide for Power BI.
Thank you, @v-chuncz-msft ,
the issue was solved by updating a gateway (which hasn't been used in the solution).
Strange, but it's working now.
