Hi all.
I've got some code (below) to list the layers in all web mappers.
It works fine when just listing the Title of the layers, but when I had a parameter to print the layer.url as well as the layer title:
"print('\t',l,layer.title)
I get the following error:

This occurs when trying to get the URL for a third party, public WMTS layer, in the Web Map.
Can I modify the code to ignore this error, or list something.
from arcgis.gis import GIS
from arcgis.mapping import WebMap
import arcpy
gis = GIS("pro")
# Search for web maps based on the query. Set max_items to -1 for all maps
webmaps_contents = gis.content.search("*",item_type="Web Map", max_items=500)
print('Number of Web Maps found: ' + str((len(webmaps_contents))))
n=0
#create web map objects from search results and print the web map title and layer name
for webmap_item in webmaps_contents:
if webmap_item.content_status != "deprecated": # Optional to include
n=n+1
print(n,webmap_item.title,webmap_item.content_status)
webmap_obj = WebMap(webmap_item)
l=0
for layer in webmap_obj.layers:
l=l+1
print('\t',l,layer.title)
print("Finished")
