Power BI Data Refresh Error

Hi Kodonnellm ,

Try manually specifying the data type for each column. Check to see if any of the records cannot be converted. Pay particular attention to records that convert text to date and datetime types.

You can turn on column quality under Preview All Data to check for conversion type errors.

Using the data profiling tools - Power Query | Microsoft Learn

You can also check which column is the problem by converting the columns to text one at a time and then refreshing.
