When Overwriting a Feature Layer on ArcGIS Online via Pro the corresponding WebHooks become unusable.
I published a hosted feature layer on AGOL using a fGDB as the source. Some WebHooks were created off the AGOL service. They functioned as expected. Later, I user ArcGIS Pro to Overwrite this service (Share Tab -> Web Layer -> Overwrite Web Layer). The Map I used held the same file geodatabase used to initially publish the service. The WebHook then stopped sending payloads. When I attempted to edit them, I received this error: 'Object reference not set to an instance of an object'. I am also unable to delete.
Pro Version: 2.6.0
fGDB version: 10.0
