## Description

### Before filing a report

17.2.2

**Steps to reproduce**

1.  Log in as a user with permission to manage project members (e.g. Project Admin).
    
2.  Open a project.
    
3.  Navigate to **Members**.
    
4.  Add a group to the project (if not already present).
    
5.  Edit the group's assigned role(s).
    
6.  Change one or more roles and save.
    

**Buggy behavior**

Editing the role(s) of a group in a project always results in an error when saving, regardless of whether a single role or multiple roles are changed.

This issue only affects **groups** within a project.

The following scenarios work as expected:

*   Editing roles for regular users in a project.
    
*   Editing group roles from **System Administration** when logged in as a System Administrator.
    

An error message is displayed (see attached screenshot).

**Expected behavior**

The updated project roles for the group should be saved successfully without any error, just as they are for regular users and when editing group roles in System Administration.

**Environment information**

<br>

*   **OpenProject version:** 17.2.2
    
*   **Browser:** Chrome _(or specify the browser you are using)_
    
*   **Operating System:** Windows _(or your actual OS)_
    
*   **Language:** Specify your browser language and OpenProject user language (e.g. English (en-US))
    

**Additional information**

The issue appears to be specific to updating **group memberships within a project**, as the same operation succeeds for individual users and for groups managed through **System Administration**. This suggests the problem may be isolated to the project-level group membership update functionality.
