How do i properly try/catch a column renamer inside a loop?

Hey everyone,

I have a component that performs a bunch of renames of columns inside of a loop which derives the renaming configuration from column names. If the input does not contain the column names necessary for the renaming configuration, the column renamer will error. However, I’m looking for zero-in-zero-out behaviour, so i tried to catch the errors with try and catch blocks like this:

What would be the correct way to catch error for the column renamer?
