Power Query Error when Refreshing

[baotrieu]

I am trying to refresh a Power Query what gets data from a SQL database and a spreadsheet that I created, can some help my understand what to look for to resolve this issue?

ERROR: YOU CANNOT REFRESH YET BECAUSE YOU NEED TO PROVIDE VALID CREDENTIALS FOR YOUR DATA SOURCES IN THE DATASET.  YOU CAN UPDATE THE DATA SOURCES SECTION ON THE SCHEDULE REFRESH SETTING PAGE.

Go to you datasets, click the ellipses, choose schedule refresh, expand data sources, click to enter credentials
