Direct Query MariaDb not working in Power Bi Online
We are experiencing the same issue, but with a custom connector. We're getting this error: "Unable to determine the data source. When custom connectors are used, the error can happen if gateway doesn't have the extension enabled." If we publish the report again, it will work for a few hours until we get the same error again. We're using a directy query source with a custom connector. Everything was working fine up until this week.
This thread is the only result for this specific error message on Google, so seems like this is a new type of issue/error.
I spent a very long time on this last week. Indeed, there was nowhere to find exactly what the problem could be or what the options were.
After I checked everything properly (On-Premise Gateway recognizes MariaDB connector, privancy levels are the same, etc) I still got the error message that the data source is not recognized.
After I added and deleted something in a file, I got the error message in Power Bi Online; "one or more cloud databases have been deleted".
When that error message came, I did manage to map a gateway connection to the On-premises, and then the error message went away and there were no more problems. Very strange how that went.
