上传图片/文件报错a.connectRuntime is not a function

表单字段动态显示时，我用文本和图片/文件字段配合适用时前端会报错
a.connectRuntime is not a function

$form->radio('type','类型')
    ->when(1, function (Form $form) {
        $form->text('con');
    })
    ->when(2, function (Form $form) {
        $form->image('con')->uniqueName();
    })
    ->options([
        1 => '文字',
        2 => '图片',
    ])
    ->default(1);
