Data flow sink bug, mapped column not being written to

John Neubecker 81 Reputation points

I have a data flow where in the transformation before a sink a column exists and has a value, key=86.

It's mapped in the sink

But it does not even appear as a column in the sink preview nor does it get inserted if I run the data flow in a pipeline. I'm not showing the preview where the column isn't there because it has other data I don't want to post here. I've tried deleting and readding the sink and that doesn't do anything. I know you'll probably try this in a simple dataflow and it will work. I've never seen this issue before. It's probably some edge case that hasn't been tested. Probably something to do with the JSON generated when you have a factory backed by git.
