Invocation Error during Change Management BPM

[JO_7001]

We have recently started using the Change BPM with a few tweaks of our own. I have been testing the various processes and assigned tasks and I have found that when we are logging a Standard Change at the point that the assigned task is to "Perform the Change" I receive the attached Invocation Error

 

I have dug around in the logs and I have found the following:

2018-11-30 12:03:26Z [INFO]:[PROFILE]:[8496] data:queryExec() Method call results: success (244293632 B, 8 ms, -32 kB, 0 ms, 0 kB)

(I have removed Names from the above and replaced with 'Username')

I have looked within Database Direct for h_sys_accounts and the accounts that are listed are none of the IT Department but random users from around the business. I have checked the BPM Process for this task and the Owner of the task is System Administrator and the task is Assigned to the Variable ["ownerId"]

 

Is there anything that you are aware of that can resolve the above?

Thanks

Are you sure the task is configured to assign to ["ownerId"]? Because looking through the logs it looks it is configured to assign to ["owner"] which is incorrect...

@Victor Thank you for coming back to me on this, I have attached a snip from the Human Task associated to this error within the BPM.

@JO_7001 - I need to have a look at this in your instance... can please create and send me (via PM) an API key I can use to investigate this, please? There is a guide for creating API keys here: https://wiki.hornbill.com/index.php/API_keys

@JO_7001 - thanks for the API key. As suspected the error occurs because the process has a human task configured to assign the task to ["owner"]. I can see you posted a screenshot where the task is assigned to   ["ownerId"] so I think there is a misunderstanding of where the error actually occurs. The error did not occur when "Perform the Change" task was created (this one is configured correctly) but on the next task, "Update Documentation". This task is configured incorrectly to assign the task to  ["owner"] instead of  ["ownerId"].
