Map Series getPageNumberFromName Error

[ScoutStanley]

I am working on converting a python script from 2 to 3. I am having issue with figuring out an error related to map series "getPageNumberFromName". 

Below is the Python 3 conversion for map series. 

ms = lyt.mapSeries
lyt.mapSeries.refresh()
pageNumber = ms.getPageNumberFromName(PIN)
ms.currentPageNumber = pageNumber

 Here is the setup for (PIN)

cursor = arcpy.SearchCursor(SourceTable)

for i in cursor:
try:
print('Start time: ' + strftime('%H:%M:%S') +'\n')
PIN = i.getValue(SearchField)
NoQuotePIN = i.getValue(SearchField)
print('\tAnalyzing parcel PIN ' + NoQuotePIN + ' ...')

#Reference aprx and layers
aprx = arcpy.mp.ArcGISProject(r'....ProMigration\AgMap_Pro.aprx')
m = aprx.listMaps("AgMap")[0]

ParcelLayer = m.listLayers("Parcel*")[0]
AgUseLayer = m.listLayers("AgUse*")[0]
SoilLayer = m.listLayers("Soil*")[0] 

Also in my script reference  lyt = aprx.listLayouts()[0] before map series section. 

Below here is the python 2 script for data driven page. The PIN is the same exact setup but references python 2. 

ddp = mxd.dataDrivenPages
ddp.refresh()
ddp.currentPageID = ddp.getPageIDFromName(PIN)

Below is the error I get when I run the script. What confuses me is the ValueError is the exact PIN that is being referenced within script.

Any ideas on what the issue is?

Issue Resolved  - Unsure if it's a workaround or not, but anyway...

within my layout in Pro, I did the steps below and instead of selecting "none" I selected the field PIN referenced and that worked. Screenshot below is from bug-000136946
