I have a service connect workflow that was working OK with one minor issue. When I updated the workflow to fix that minor issue, I got the following error on the first call to Epicor:
error type:unexpected error
error number: 2147220990
error description: Unspecified error: Unknown fatal errors occurred: Failed to execute proxy assembly for imported .NET class library due to session creation failure
The new updated workflow was designed on my development environment first and imported into the pilot system. The new workflow works OK on my development environment. On the same pilot system, I have another workflow that makes the same call and is working OK.
That was my first response to that error.I fix session creation error before by re-importing .NET reference. But not this time. I have another workflow on the same box that is calling the same .NET dll and the same method without any problem. Initially I thought my workflow may be corrupted during the exporting and importing process so I did that multiple time and no luck. I already got hold with Epicor support. I will update this topic if I get it resolved.
Yes, I did. Sorry I forgot updating this topic. I have a company ID hard coded in my workflow. The company ID is my test company ID. I thought I changed it when I migrated to the pilot system, but I must have not saved the change.
Same Error is happening at my side: Unspecified error: Unknown fatal errors occurred: Failed to execute proxy assembly for imported .NET class library due to session creation failure
I deleted the .Net Reference, and at time of re-import I realized that I am selecting the wrong .sysconfig file…
