DirectQueryUnexpectedEndOfStream PowerBI Desktop

[steeleman5000]

Getting this error when refreshing on PowerBI Desktop.  I had put in a query parameter to limit rows when loading, it worked fine initially but isn't now.  

Error Message:
Internal error DirectQueryUnexpectedEndOfStream.

Stack Trace:

Hi @steeleman5000 ,

There might be some transformations in your M query that Power BI service is not able to handle. If you have any complex calculations or joins in your query, try separating them out into separate tables or steps.

Best regards.

I know this is a bit old, but I just had this issue and was able to resolve it using a Table.StopFolding step after the initial connection.  This prevents any transformations beyond a basic select statement, so my assumption is that the Power BI Service handles this differently.  You can verify this by viewing the source query in the transformation steps.
