Workflow issue with timeline

Are all workflow steps out of the box ones - or are any custom steps. I want try and reproduce this model to see if I get this issue. 

They are all out of the box. 

Workflow component group:

3 no operation steps (Initiator, approve and reject).

1 participant steps (assigning to content-authors group)

WCM Workflow:

1 Activate  page/asset

I can provide a larger image if necessary.

Cheers,

I re-created the workflow

The only difference is i put a DeleteNode step after reject. 

It worked without issue and the payload (the page) was deleted after i rejected. 

For the part step - make sure you set to a valid user - i tested with admin. Also - try invoking from a page here: 

http://localhost:4502/siteadmin#/content

see if that works. 

Hum, I wonder if it is because the workflow you recreated assigns to a particular user (Administrator) rather than to a group (content-authors).

To clarify, the review steps assigns to authors (content-authors) I then sign in as a content-author I created for the purpose of testing and that's when the error is thrown.

Said user has all of the properties set include first name and last name that normally make up a display name.

Try that and try invoking from classic UI (http://localhost:4502/siteadmin#/content) too. Lets see if the issue can be nailed down. 

yup, same problem when starting it from classic UI, same error too.

Did you try and set to admin in part step? 

yeah I did, and that worked. the problem is only when setting to groups

Groups that aren't administrators
