'updates' parameter is valid, Geometry update is not allowed.

Hello.  We have a python script running in Windows Task Scheduler.  The script retrieves vacant parking space counts from a vendor's database through their API.  The counts are updated every minute in our editable feature service, displaying the current number of vacant parking spaces in a couple of municipal parking lots.  In the past few days, I noticed the counts were not updating.  The script has been working since November 2019, though I don't know when it stopped.  We have not edited the script since placing it into production in November 2019.  ArcGIS Pro is installed on the server, we updated Pro to v 2.7 today.  For troubleshooting, I ran the script manually, and noticed the following error.  I am a Python novice.

I may have figured out the cause.  In the hosted feature service Items page in AGOL, I found a geometry update option in "Settings....Editing...What kind of editing allowed?"  Under 'Update,' there is a choice to include 'Attributes and geometry.'  I clicked on "Manage geometry updates" and discovered the feature layer in the service was not selected.  I clicked the layer on. Saved.  Refreshed, ran the script and no errors.  I refreshed the application in the browser and could see the vacant space counts were updating each minute and the script was now working as expected.
