ExporttoPNG Python for MapSeries

[ElizabethAyarbe]

I'm trying to export my ArcGIS Pro map series to PNG.  I'm using the MapSeries example code #2 from Esri (http://pro.arcgis.com/en/pro-app/arcpy/mapping/mapseries-class.htm ).  I keep getting an Invalid page number error. 

Any help is much appreciated!!

See below code and error:

Code:

import arcpy, os, sys
relpath = "Z:\\41708.02 VAGuidehouse - MAHSO Call 1\\300TIG\\315Maps\\Maps_DDF"

aprx = arcpy.mp.ArcGISProject("CURRENT")
l = aprx.listLayouts()[0]
if not l.mapSeries is None:
ms = l.mapSeries
if ms.enabled:
for pageNum in range(1, ms.pageCount + 1):
ms.currentPageNumber = pageNum
print("layoutName{0}".format(ms.pageRow.Market))
pageName = ms.pageRow.Market
l.exportToPNG(relpath + "\\PNG_Test\\S7_MKTOVW_{0}".format(ms.pageRow.Market) + ".png")

Error:

Traceback (most recent call last):
File "<string>", line 10, in <module>

Sorry, I confused the posts/names.  Same intention to help.  I will look at your other post.

I'm late to the party but this thread was helpful to me, so thanks Elizabeth for making the post. I modified your script ever so slightly and it ran just fine for me. Here is the snippit that I used:

import arcpy, os, sys
relpath = r'''F:\0 - Ranking All Unknowns\insetmaps'''

aprx = arcpy.mp.ArcGISProject("CURRENT")

for item in aprx.listLayouts():
 itemname = item.name
 print(itemname)

l = aprx.listLayouts()[5]
print(l.name)

ms = l.mapSeries
for pageNum in range(1, ms.pageCount + 1):
 ms.currentPageNumber = pageNum
 pagename = ms.pageRow.Invnum
 print("{}".format(pagename))
 filename = pagename + ".png"
 print(filename)
 endlocation = os.path.join(relpath, filename)
 print(endlocation)
 l.exportToPNG(endlocation)
