Error assigning role: There is no role named `Admin`

I can't get roles to be able to be assigned to users.

My function that assigns user roles is as below, but it returns the following error - [2023-06-26 17:59:58] local.ERROR: Error assigning role: There is no role named Admin.

This is my laravel log

As you can see Admin is in the roles list, it exists in the database table, I've tried debugging lots of ways but can't find any solution that works

public function assignRole(Request $request) {

Log::info('Data received: ', $request->all());
\Log::debug('Request details:', ['data' => $request->all(),]);
$roles = Role::all();
Log::info('Available Roles: ' . $roles->pluck('name')->implode(', '));

try {
    $users = User::find($request->users);
    Log::info('User: '. $users);
    $roleName = $request->role;
    Log::info('roleName: '. $roleName);
    $teamId = 1; // default team id for general roles
    Log::info('teamId: '. $teamId);

    $guard = 'web'; // specify your guard name here
    Log::info('Guard: '. $guard);

    $role = Role::where(['name' => $roleName, 'guard_name' => $guard])->first();
    Log::info('Role: '. $role->name);

    $users->each(function ($user) use ($role, $teamId) {
        $userGuard = $this->getGuardName($user);
        Log::info('User Guard: '. $userGuard);
        if ($userGuard === $role->guard_name) {
            $user->assignRole($role->name, $teamId);

        } else {
            \Log::error('Error assigning role: User guard and role guard do not match.', ['user' => $user, 'role' => $role]);
        }
    });

    if ($role) {
        Log::info('Role: '. $role);

        \Log::debug('Fetched role:', ['role' => $role,]);

        $users->each(function ($user) use ($role, $teamId) {
            $user->assignRole($role->name, $teamId);
        });

        return response()->json(['message' => 'Role assigned successfully'], 200);
    } else {
        \Log::error('Error assigning role: Role not found.');
        return response()->json(['error' => 'Role not found'], 404);
    }
} catch (\Exception $e) {
    \Log::error('Error assigning role: ' . $e->getMessage());
    return response()->json(['error' => 'Error assigning role'], 500);
}

}
