I have admin role, but I can't get project roles for project

[Бурак Андрей]

Hi!

I am trying to get project roles. I have admin role, but when i do GET /rest/api/2/project/{projectIdOrKey}/role I get error message:
errorMessages: [ 'Вы не можете редактировать конфигурацию этого проекта.' ]
(On en: You cannot edit the configuration of this project)

Please tell me how to fix the error.

Thank you so much

It's not possible to disable it (although the request has already been raised)

To put a mostly-acceptable block on it though, simply make sure all your workflows are used by more than one project (even if it's an inactive or hidden project).  As soon as a workflow is shared, project admins can't change it.
