I have developed a workbench in 32-bit FME 2021.1.1.2 which is reading ArcSDE DB with ArcFM (32-bit) and 64bit background processing installed. I have ArcGIS 10.6.1 installed. This workbench has been published to 64bit FME Server 2021.1.0.1. The error i am getting after setting up the scheduler in FME Server is "Could not open Enterprise Geodatabase. The error number from ArcObjects is : -2147.... The error message from ArcObjects is : {Underlying DMBS error Unknown errorNo Extended error.]}"
The workbench runs fine in a standalone mode without FME Server. Is the issue due to compatibility issues between 64-bit FME Server and 32-bit ESRI products or the the version difference between 2021.1.x between FME Desktop and FME Server ?
