We have a pair of nightly maintenance workbenches that clean up feature class attributes via Portal connections. When I manually trigger these workbenches to run, they complete without fail. However, about 80% of the time that they run overnight via FME Server, they fail with the following error:
ArcGIS Portal Feature Service Writer: Error code 400 Message - 'Unable to complete operation' Details: This operation is not allowed while editing AutomatedProcess_DONOTDELETE]
These Workbenches are trying to Update, No Truncate first. Is this a branch versioning issue?
I have done some digging but haven't found anything specific to this particular error other than the ESRI help page saying that "It is rare and causes are unknown."
Any insight is greatly appreciated.
