Dataflow refresh started failing today MashupException.Error
Hi! I've had about 90 dataflows set up for a few months now. Last night all but 2 of them failed with error MashupException.Error The two that succeeded were very small tables with less than 100...
Also, I should add that of the cases of "104100 Couldn't refresh an entity because of an internal error", they were all because the GW server could not establish connection to the SQL endpoint of the destination LH.
We'll need GW logs to confirm that, but you can quickly try this on the GW server too: make a TCP connection to the LH SQL endpoint, port 1433, and see if that's successful. If not, then you are inside some kind of firewall that has allowlisting only for staging lakehouse and not for the output.
pqian_MSFT btw, could the old version of SQL Server we are using be an issue?
