Jira project all permissions from permission schema include users

[Or ate]

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.

Hi @Or ate and welcome to the community,

Your user data is private to you, I'm afraid. So I would suggest you start by having a look in Jira itself and investigate:

• the permission scheme that you are pulling the data from in Jira and the detailed permissions;
• the users assigned to project roles inside the project itself;

That should explain who those users are and where they come from.
