I have two similar issues with the new Form nodes.
The first one is that it return the Error 500 if there is only the trigger node and Form ending node (no Next Page nodes in-between)
The second issue is with the Form ending node, which becomes broken if I sent an expression to it
Both issues will result in Error 500, but with different error text.
For the first one:
