STEPS TO REPRODUCE:

Link the Start and Finish steps and validate it
3. To an existing user give the following instance level rights:
Process - Start for "project process 1"
4. Go to Studio > Project object
5. Actions tab, create an action to execute the process above
6. Views tab > Project properties View > Actions Menu
7. Add the action we created on step 5
8. As the user with the instance right, go to a project and execute the action we created.
Expected Results: A pop-up displays telling you the process was initiated
Actual results: A pop-up displays telling you there was a problem initiating the process and to contact the administrator
