Hey,
Wanted to update and summarize the issue.
Issue - In general there are issues with connections to MySQL DBs from Power BI. The symptom in my case was that data refresh did not work and failed with the error message in my first/original post.
Solution - Creat a connection string to MySQL DB with the query in it. For example:
= MySQL.Database("localhost:3306", "DB_Name", [ReturnSingleDatabase=true, OldGuids=true, Query="select * from MyTable where MyCondition"])There is no need to delete or re-create the original connection string. Just to update it.
Thank you GilbertQ and v-frfei-msft for your assistance.
Cheers!
