I haven't been able to publish to portal for months now. I can successfully publish from file geodatabases, and I can copy from my sql database, but cannot publish referenced data from the sql database. I know this was possible in the past.
I've upgraded by database, I am using my editor login to the database with portaladmin login. My databases validate before I publish and then I get the error when trying to publish, go back to validate and they are no longer validated.
Any insight is greatly appreciated with this issue!
