When I ran first step in the workflow (Create Job) for the first time I got this error

---------------------------

Workflow Error

---------------------------

An error occurred while trying to execute this step. External component has thrown an exception.

---------------------------

OK  

If I run it again it will work perfectly

Any idea?

that error message goes back 7 years and is related to a number of things.  A lot of it has to do with things that have been fixed in updates of various software.

What are you using in terms of operating system etc etc... something is out of date

Am using esri workflow 10.5.1

OS: Windows server 2012 R2

ArcGIS Dektop 10.5.1

Any more details needed?

check the system requirements

I presume that if 10.5 runs, then it should be fine, but you are using windows server os
