Object reference not set to an instance ONLY when the WFLW is called by another WFLW

Hello All,

 

I have built a sub workflow that goes and creates a database item for members of a group.

The workflow has a step for creating a reference from a database using list method, then goes onto another step that is for each and does the creation of an item on a different database.

the workflow when started manually or by a separate form works just great. however when I call this workflow from a parent workflow I get this error on the reference creation step:

 

28083 ServerEvent: Object reference not set to an instance of an object.
InnerException: Exception has been thrown by the target of an invocation.
InnerException: Object reference not set to an instance of an object.

 

I am using the K2 service to start it from within the other workflow. 

 

Any ideas on why it would work only when not called by a parent workflow?

 

EDIT

 

After digging I find in the host server log this message :

 

"18545013","2016-02-01 10:21:32","Error","General","0","ErrorMessage","Default Activity","0 Object reference not set to an instance of an object.","anonymous","0.0.0.0",

 

Any one have any ideas?

When you started the workflow on its own, did you use the service account as well?

Yes.

 

Now the issue is even weirder, just trying to create the same reference in a K2 designer workflow and getting that error. without even calling a second workflow. 

 

gives the same error.
