Hi, I tried to summarize all my permissions on the project.
I use the api:
/rest/api/project/{project_id}/permissionscheme with the param : {"expand": "all"}
and got a list with all permissions.
Most of the permissions are projectrole type and all is ok.
Part of the permissions are user and in the items that are from type user I don't have the full data of the user, not the user_id , username or something that can help me understand who is this people.
