Unexpected null error

Actions & Logic

I created a simple social media tab that allows you to comment and like posts, all of this is working. But when I add a button that takes the user to another tab, which allows editing or deleting the post, it shows this error

What have you tried so far?

I didn't quite understand the error, after all, the user is obviously authenticated and I am passing a non-empty parameter to the other screen. I also tried to check my firebase rules, but I didn't understand the error.

Did you check FlutterFlow's Documentation for this topic?
