firebaseにnext.jsアプリをデプロイしたいがエラーが発生する
解決したいこと
このサイトを参考にfirebaseにnext.jsをデプロイしたいです。
このようなエラーが出てしまいnpm run serveができません
TypeError: next is not a function

助力頂きたいです。
該当するソースコード
当コードが悪さをしているのは理解できますが、何故悪さをしているのかが理解できず。
firebaseFunctions.js
const { join } = require('path')
const { https } = require('firebase-functions')
const { default: next } = require('next')
const nextjsDistDir = join('src', require('./src/next.config.js').distDir)
const nextjsServer = next({
dev: false,
conf: {
distDir: nextjsDistDir,
},
})
const nextjsHandle = nextjsServer.getRequestHandler()
exports.nextjsFunc = https.onRequest((req, res) => {
return nextjsServer.prepare().then(() => nextjsHandle(req, res))
})
自分で試したこと
package.jsonのfirebase関連のバージョンが古いので新しくした上でnpm iをしました。
(nextjsは対応しているバージョンが13.4.7なのでそちらに合わせています。)
