I set up a .gdb that includes a feature class of locations and a related table of inspections. One of the domains is a list of existing location categories that will be updated occasionally as new are discovered. In trial runs, I appended the domain using the table to domain tool in ArcMap successfully but get the following error when attempting to publish as an overwrite to an existing service to AGOL. “Packaging succeeded, but publishing failed. ERROR: code400, Unable to delete item. This service item has a related Service item, Bad syntax in request.” Delete Protection is disabled on the hosted feature layer. Any thoughts on why I can’t overwrite the feature layer in AGOL after appending the domain in ArcMap? Maybe a different workflow?
