I am trying to connect (get data) to one of the MySQL databases and receive an error: "An entry with the same key already exists".
I can't even see what tables are available.
When I use native SQL query or try to connect to other DB then problem doesn't occur.
Hi, @technolo_bi ;
Clear permissions in data source settings and try the latest version of Power BI Desktop.
It seems that the error is essentially a duplicate column name error,

Hi @v-yalanwu-msft,
I can't even select a table, so where should I look for duplicate column?
I have the same problem. Thanks in advance for any help!
