Ran into this issue myself within the Power BI Desktop and was able to resolve the issue through the following:
- Select Edit Queries from the menu to open the Query Editor

- In the top menu bar, select Refresh Preview.
In my case there were several queries having this same issues and the steps above resolved each of them.
