I am getting this error message when using the center output. "system error: null"
This flow was working previously. I updated a few of the early steps and added the union. Since then I have been getting the error.
To get around this, I right clicked the step before my output and chose to "preview in tableau" and the data exported to tableau fine. I then exported the data to csv from Tableau to continue my work.
The other two outputs in the flow seem to work fine.
Any idea what's going on?
