vue3项目中structuredClone报错

报错：Failed to execute 'structuredClone' on 'Window': #<Object> could not be cloned

代码：

const formData = ref({"content": "", // string"id": "", // string"title": "", // string
})
const formDataLocal = ref(structuredClone(formData))

修改：formData不能是ref格式，改为如下

const formData = {"content": "", // string"id": "", // string"title": "", // string
}
const formDataLocal = ref(structuredClone(formData))

原因：待补充
