Symptoms

Happens when trying to deploy a process, the following error occurs here, "Object reference not set to an instance of an object
 

Diagnoses

When you have been creating a process using K2 Studio and when loading up the deployment side this fails with the following:

"Object reference not set to an instance of an object".

Is there a way to get past this error ?
 

Resolution

If the events within the activity have been copied and pasted then this can cause an issue here, so for future reference it is a good idea not to do this approach. The only way to get around this is to re-do the copied events or activities as a whole in order for this to be deployed here.
