Passing Parameters red code

Actions & Logic

I would much appreciate help from anyone who understands a red code

I am trying to pass the parameters following the FF video tutorial on YouTube and I keep receiving this red code

What have you tried so far?

I have reviewed several times that all the default values are settled in order to avoid "unexpected null value", and everything seems to be ok.

I have overcheck that I am passing a document.

I have tried to figure out "which thing can be a null value".

Did you check FlutterFlow's Documentation for this topic?

Yes
