Help needed: in an action, how to ask the user to enter some text via input()

[Joachim_Mund]

Hi all,

from a card view I give a user the possibility to decline something.
This trigger an action “Data: set the values of some columns in this row”.
One of the columns to be set should prompt the user for some text via input(“Ablehnungstext”, “”)
But the input box is empty and no input field is shown.

What I’m doing wrong?

Thank you for all help!
