多级联动无法获取信息

[sudo-vector]

• Laravel Version: laravel 9.58.2
• PHP Version: 8.1.10
• Dcat Admin Version: 2.2.2

Description:

我设计了现员工管理的多级联动功能
protected function form()
{
return Form::make(new Team(), function (Form $form) {
$form->display('id');
$form->select('branch_id', '分公司')

        ->options(Branch::all()->pluck('name', 'id'))
        
        ->load('department_id', 'api/employee?type=department&q=:branch_id')
        ->required();
    
    $form->select('department_id', '部门');
        ->options(function ($id) {
            \Log::info('Department options callback with branch_id:', ['branch_id' => $id]);
            
            // 这里应该返回部门列表，假设Branch模型关联了Department模型
            return Department::where('branch_id', $id)->pluck('name', 'id');
        });
       
        $form->text('name', '组名')->required();
    
        $form->text('manager_id');
       
      
    
        $form->display('created_at');
        $form->display('updated_at');
    });
}

发现api调用成功[2024-12-26 03:20:17] local.INFO: Cascade Request {"type":"department","parentId":"1"}
[2024-12-26 03:20:17] local.INFO: Cascade Response {"options":{"Illuminate\Support\Collection":{"1":"企业部","2":"人才组","3":"企业部"}}} ，但是department $id 为null,无法select 部门
