Calculate Field: Python Code Block: GP Tool Not Passing All Parameters to Code Block's Function

[ZianChoy]

I tried running Calculate Field with a code block that defined a function:

def test(incdt, t):
    result = None
    if t != "":
        result = incdt.date() + datetime.timedelta(seconds=float(t))
    return result

I ran the GP tool with the following expression:

test(!Time_Sent_To_Queue!, !F1st_Unit_Assigned!)

But, Pro says that its own GP tool isn't passing both fields. The GP tool returns:

TypeError: test() missing 1 required positional argument: 't'

I'm running Pro 2.8.0 on Windows 10.

What would make Pro fail to pass both fields to the function? The 2 source fields are of type Date and Text respectively. The destination field is a Date field.

try adding

import datetime

before the def line

also, try switching the order of the parameters in the def to see if it still errors out
