TypeError: fetch is not a function

my code was just working at least 5 hours ago and now is giving me this error

TypeError: fetch is not a function

const fetch = import('node-fetch')
const getUUID = async function(un){
    let uuid
    await fetch(`https://api.mojang.com/users/profiles/minecraft/${un}`)
    .then(res=>res.json())
    .then(json=>{
        try {
            uuid = {result: true, uuid: json.id}
        } catch {
            uuid = {result: false, uuid: null}
        }
    })
    return uuid
}

this code is supposed to just return the result and id but instead, it says fetch isn’t a function, am I doing something wrong?

My Environment

software	version
node-fetch	3.1.0
node	16.11.1
npm	8.0.0
Operating System	Microsoft Windows [Version 10.0.19044.1348]

Fixed! Here is the code:

const fetch = import('node-fetch')
const getUUID = async function(un){
    let uuid
    await fetch.then(async data=>{
        await data.default(`https://api.mojang.com/users/profiles/minecraft/${un}`)
        .then(res=>res.json())
        .then(json=>{
            try {
                uuid = {result: true, uuid: json.id}
            } catch {
                uuid = {result: false, uuid: null}
            }
        })
    })
    return uuid
}

vscode (typescript) will have a harder time of knowing what the return type is if you assign uuid later like that… it’s better to have a return instead.

few examples if you want to keep import at top:

const fetch = import('node-fetch')

const getUUID = async function(un){
    const uuid = await fetch.then(async data=>{
        return data.default(`https://api.mojang.com/users/profiles/minecraft/${un}`)
        .then(res=>res.json())
        .then(json=>{
            try {
              return { result: true, uuid: json.id }
            } catch {
              return { result: false, uuid: null }
            }
        })
    })
    return uuid
}

const fetch = import('node-fetch')

const getUUID = function(un){
  return fetch.then(data => {
    return data.default(`https://api.mojang.com/users/profiles/minecraft/${un}`)
    .then(res => res.json())
    .then(json => {
      try {
        return { result: true, uuid: json.id }
      } catch {
        return { result: false, uuid: null }
      }
    })
  })
}

const fetch = import('node-fetch')

const getUUID = un => fetch
  .then(({default: fetch}) => fetch(`https://api.mojang.com/users/profiles/minecraft/${un}`))
  .then(res => res.json())
  .then(json => {
    try {
      return { result: true, uuid: json.id }
    } catch {
      return { result: false, uuid: null }
    }
  })

const fetch = import('node-fetch')

const getUUID = un => fetch
  .then(({ default: fetch }) => fetch(`https://api.mojang.com/users/profiles/minecraft/${un}`))
  .then(res => res.json())
  .then(json => ({ result: true, uuid: json.id }))
  // fallback if any of the above fails (load module, parse json, or get id of json)
  .catch(err => ({ result: false, uuid: null }))

const fetch = import('node-fetch')

const getUUID = async function (un) {
  const url = `https://api.mojang.com/users/profiles/minecraft/${un}`
  const { default: _fetch } = await fetch
  const res = await _fetch(url)
  const json = await res.json()

  try {
    return { result: true, uuid: json.id }
  } catch (err) {
    return { result: false, uuid: null }
  }
}
