Hi. We recently upgraded our environment to version 10.5 and I am now unable to successfully execute a simple geoprocessing service. The gp service broke after the 10.5 upgrade (for a known reason). I fixed it and successfully published it. However, it fails with error 000732 when run. With this error message:

The error message is actually correct. ...SQLSAZD02_GdbGisuPub.sde\BoundaryCountyPolgyon does not exist. The feature class reference is missing "GdbGisuPub.GISU" in front of BoundaryCountyPolygon.
My script references "GdbGisuPub.GISU.BoundaryCountyPolygon" (or it wouldn't work). Somehow during publishing it gets changed.
Does this look familiar to anyone? Anyone know what I am doing wrong now?
Thanks.
