Question

我正在构建一个无头 wordpress CMS（并使用 next.js 模板）。

我能够成功部署到 vercel 服务器，然后我开始添加一些内容，在这种情况下是 Wordpress 的标题字段。当我更新我的 git 时，它会终止 vercel 部署并出现此错误。如果我尝试使用内容或危险的 SetHTML，我也会收到此错误

澄清一下，如果我删除它，它部署得很好 { page.title }

这是我的页面代码 [slug].js


import Head from 'next/head'
import Link from 'next/link'
import Container from '../components/container'
import MoreStories from '../components/more-stories'
import HeroPost from '../components/hero-post'
import Intro from '../components/intro'
import Layout from '../components/layout'
import { getAllPagesWithSlug, getAllPagesBySlug } from '../lib/api'
import { CMS_NAME } from '../lib/constants'
import Header from '../components/header'


export default function Page( {page} ) {

  return (
    <>
      <Layout>
        <Head>
          <title></title>
        </Head>
       <Header />
        <Container>
        
        { page.title }
          
        </Container>
      </Layout>
    </>
  )
}


export async function getStaticProps({ params }) {
    
  const data = await getAllPagesBySlug(params.slug)
  console.log(data)
  
  
  return {
    props: {
      page: data.page,
  
    },
  }
}

export async function getStaticPaths() {
  const allPages = await getAllPagesWithSlug()

  return {
     
     //paths:  [ { params: { slug: '${node.uri}' } }  ],
    paths: allPages.edges.map(({ node }) => `/${node.slug}`) || [],
    fallback: true,
  }
}

这是我的查询 lib/api

const API_URL = process.env.WORDPRESS_API_URL

async function fetchAPI(query, { variables } = {}) {
  const headers = { 'Content-Type': 'application/json' }

  if (process.env.WORDPRESS_AUTH_REFRESH_TOKEN) {
    headers[
      'Authorization'
    ] = `Bearer ${process.env.WORDPRESS_AUTH_REFRESH_TOKEN}`
  }

  const res = await fetch(API_URL, {
    method: 'POST',
    headers,
    body: JSON.stringify({
      query,
      variables,
    }),
  })

  const json = await res.json()
  if (json.errors) {
    console.error(json.errors)
    throw new Error('Failed to fetch API')
  }
  return json.data
}

export async function getAllPagesBySlug($id) {
  const data = await fetchAPI(`
    {
     
        page(id: "${$id}", idType: URI) {
            uri
            slug
            content
            title
            featuredImage {
              node {
                sourceUrl
              }
            }
          }
    }
  `)
  return data
}

显示道具时仅在 vercel 部署时出现错误（在本地工作）
