Hi! We just realized that we haven't looked into this PR in a while. We're sorry! We're labeling this issue as Stale to make it hit our filters and make sure we get back to it as soon as possible. In the meantime, it'd be extremely helpful if you could take a look at it as well and confirm its relevance. A simple comment with a nice emoji will be enough :+1. Thank you for your contribution!

@zmoog Correct me if Im wrong please, I thought rename automatically remove the old fields. So no need to add remove here anymore.

[MakoWish]

I am not sure why that remove processor is showing as added in my branch. I did not add those. Did another PR remove them, so now my changes appear to be adding them again?

[kaiyan-sheng]

ahh ok lets remove them from this PR then :) Thanks!

[MakoWish]

Done! :-)
