autoIncrement not working in ArcGIS Pro field calculate

Question

After we upgraded to ArcGIS Pro version 3.3.1 we are no longer able to run the autoIncrement script to populate values in a field calculate. Attached is the error we're seeing where it is referencing a function was not found. Has anyone come across this issue?

rec=0 
def autoIncrement(): 
 global rec 
 pStart = 1  
 pInterval = 1 
 if (rec == 0):  
  rec = pStart  
 else:  
  rec += pInterval  
 return rec

I believe it is trying to run a function named "WF-"=. which isn't defined and should be calling the autoIncrement function.

I think the FACILITYID = line should be autoIncrement() and the concatenation and zfill should be handled in the function/returns.

Not sure what version of Pro this is from, but in 3.1.3 it is SequentialNumber helper and the top line tells it what function to execute:

R_

So the odd thing is I hit Apply/OK and it would give an error saying I need to correct whatever is wrong before the calc can take place (that part seemed to be new in 3.3.1 - I want to say in the past versions it would let you click Apply/OK). After a few times of doing that, I tried again and I was able to see it go through.

If you ignore the error and hit Apply/OK, does it work correctly?  It might be a validation defect for the expression rather than an actual error in the expression.
