connecting localhost database to PowerBI

Hi,

I have create a local SQL database using  phpmyadmin, and I wanted to connect this data base to Power BI. So I tried to follow the example created by your team in the Youtube channel https://www.youtube.com/watch?v=ggpn3-4FB4s

Hence, I put the localhost as name for the server and I put the name of the data base, Unfortunately I had this problem "An error occurred while reading the data: 'The object reference is not set to an instance of an object "

Can you please explain to me this error? and help to read this SQL database?
Thank you for your help.
