DAX studio error v2.8.4 vs v2.8.2- export csv file - "Object reference not set to an instance of an object" #175

Hi all,

I often export data tables via DAX Studio towards CSV files (Evaluate [TABLE]) . This always used to work, up until the most recent update from DAX Studio.

  • In version 2.8.4, it does not work anymore.
  • When reinstalling the old version 2.8.2 , the export works again.

The error I keep on getting is: "Object reference not set to an instance of an object".

Any idea why all of a sudden this error is popping up as from DAX Studio version 2.8.4? What could the reason be?

Many thanks,

Hi there, thanks for logging this. I added some code to consistently quote string fields in response to another issue, but the tests I ran did not include tables with null values. This error only occurs when fields in the table contain nulls.

I have a preview build of 2.8.5 available here which includes a fix for this if you would like to test this

@dgosbell thank you for the quick fix. We had the same export issue with the new release which was resolved with the 2.8.5 preview.
