I have a SharePoint (MS365) list that I am using Parcel Number field to Geocode. The geocode source data on AGO is a parcel HFL. Before converting my excel table to a SharePoint list, I tested in APro. I did a join between the parcel HFL and the excel table and was able to get 100% match. The same table was used to create my SharePoint List. However, once I setup a workflow and let it run, the entire SharePoint site became inaccessible when it almost reaches 90%+ completion. During this period, I got the same error when accessed through my phone or private/incognito mode on my PC. After 2-3 minutes, the site would return, but when I looked at the field I created for the Workflow, just over 50% completed geocoding. The rest was blank. None of "In Progress" or "Cancel" status, just blank. I repeated 2 more times by creating a new SP list but I got almost the same result. My excel/SP list has 249 records.
I notice I could trigger the Workflow of the list item with blank value by changing the APN to an incorrect APN then changed it back. However, it is not a fun process to do this manually regardless of quantity.
Has anyone had similar experience of geocoding failure and found workarounds? Thanks.
