This may look like a duplicate post, which @Clubdebambos solved. But although that solution worked for updating item thumbnails, my script still fails when trying to update group thumbnails. Unfortunately there appears to be no equivalent "update_thumbnail" method for the group object. I updated my test script to target a group:
# To recreate problem
# 1. Update the GROUP_ID variable below to an ArcGIS online group id that you own
# 2. Copy this entire script file and paste it into the ArcGIS Pro (make sure you are signed in)python analysis window, hit enter twice
# 3. Enter run_test()
GROUP_ID = 'e3fb48baf4834208bb545894c3fb7e6a'
from arcgis.gis import GIS
import requests
import os
def test_upload_as_thumbnail (group, path):
try:
group.update(thumbnail = path)
print (f"Upload {path} to {group.id} as thumbnail succeeded")
except Exception as ex:
print (f"Upload {path} to {group.id} as thumbnail failed: {str(ex)}")
return
def test_download (url):
if url.lower().startswith('http'):
try:
requests.get(url).content
print (f"Download {url} succeeded")
except Exception as ex:
print (f"Download {url} failed: {str(ex)}")
return
def run_test():
gis = GIS('pro')
for url in ['http://maps.fieldmuseum.org/apps/ROWHWG/icons/FeatureLayer.png', # this one works
'https://rightofway.erc.uic.edu/wp-content/uploads/FeatureLayer_600_400.png', # this one fails
'https://rightofway.erc.uic.edu/wp-content/uploads/FeatureLayer.png']: # this one fails
test_download (url)
test_upload_as_thumbnail(gis.groups.get(GROUP_ID), url)
