Issue connecting to mariadb from datamart

[mark-alford]

Unable to connect to a maria db from the datamart, have no issues connecting when using powerbi desktop, and with setting up scheduled refresh using an on-premise gateway connector with powerbi online.

Error is either "An exception occurred: 3 arguments were passed to a function which expects between 1 and 2."

or "Unexpected error" depending on if I specify the database in the datasource (which from the placeholder text should be valid).

Hi @mark-alford ,

Recently we have received feedback about problems connecting to Maria DB, and in most cases there are problems with invalid credentials.
I tried to reproduce your problem but it didn't appear the same as yours.
Is this a temporary problem and does the problem still exist?

The MariaDB connector is now no longer available as a source in the PowerBI Datamart?

I don't get as far as credentials, the connector is missing from the list when creating a datamart.
