Null is your only clue so far. Its coming from somewhere. You'll need to follow the method of the community poster and start tracing/printing variables until you find what NULL is being passed. |

I'm telling you there's no null values in the final DF. And the error is thrown by tableau prep shortly after the flow starts running yet the script still completes without issue. |
