Dataflow Refresh Error in Power BI Service

Due to big data (millions of row) we work with dataflow created in power bi service and we have license PPU.
Until before 2 days the dataflows were refreshed ok. Suddenly yesterday we faced the error as below.
In one mement the refresh it was successful but didn’t retrieve the full data (rows were missing) and again failed.
We tried to create new dataflows, with 10 rows or less from the same source and the refresh failed again.
I checked:

  1. Gateway - ok
  2. Odbc connector - successfully connected
  3. I can access the data and create the dataflow in power query pbi service. The SAVE step successfully
  4. Refresh failed :frowning:

Please your support and help!

Thank you in advance!

Did you previously have a column named _id in the data?

In the error message you posted the below text stood out

The column ‘_id’ of the table wasn’t found.

Has this column been removed or renamed? This could be the cause.
