Fixing Zapier webhook for Upsert Catalog Object endpoint

Hey @Bryan-Square and @goalight912 I am still having this issue.

The first time I run the automation, it works, but the second and subsequent times I get this issue.

I want to create new items to go in existing categories, not create new categories. Can you help me out with the syntax of that?

Thanks!
