我的nuxt.js项目显示了此问题：
[Vue warn]: The client-side rendered virtual DOM tree is not matching server-rendered content. This is likely caused by incorrect HTML markup, for example nesting block-level elements inside <p>, or missing <tbody>. Bailing hydration and performing full client-side render.

我知道问题的含义，但是如何找到该地点？ 似乎没有给出错误的代码位置信息。
EDIT-01
在我的layout/default.vue中，添加<Header/>之后，它引起了问题。
<template>
<div>
<Header></Header>
<nuxt/>
</div>
</template>
我的标题就是这样的结构：
<template>
<div class="main-body" >...</div>
</template>
