Direct Query MariaDb not working in Power Bi Online
I'm having this exact same problem within the last couple of weeks. Had a report that was doing a scheduled refresh. All has been well. A couple weeks ago, it stops refreshing from the MariaDB through a Gateway. If I pull it up in Power BI Desktop, it works just fine. If I re-publish the report, it seems to work okay in the service for a couple hours, but then eventually fails the scheduled refresh.
The report shows the same error as above... "Cannot load the model."
The dataset error shows "Unable to determine the data source. When custom connectors are used, the error can happen if gateway doesn't have the extension enabled. Details: undefined."
For some reason it works at the moment, but i have absolutely no idea how it worked. After some tries i got the message : "some cloud databases were deleted" and after that i could connect to a gateway. Very strange
