ReferenceError: Request is not defined

[AlexanderBachSchmidt]

Summary

Hi,

Suddenly my code is giving this error when deploying on Vercel. I tried tons of things to fix it but nothing seems to work. When I run it locally whether with "next dev", "vercel dev", "vercel build", it doesn't give any error.

What could be causing this and what is the best way to debug it?

What version of Node.js have you got on your Vercel deployment? If it is 16.x, or less, then you should set it to 18.x, assuming that none of the packages you are ussing, require lower Node.js versions.

Basically, you should have the same Node.js version, locally and on Vercel.

Figuring out the Node version on Vercel: https://vercel.com/changelog/node-js-version-now-customizable-in-the-project-settings

Thank you, I've come across the same error yesterday and couldn't figure out what was wrong suspecting different packages. You saved the date. What a coincidence!

Much appreciated!

Node.js v20.16.0

[jvmhonorato]

To solve this on Windows: download the latest LTS version: https://nodejs.org/en/download

To solve this in WSL 2 (Linux):

Step1: First, let’s install Node Version Manager (nvm), which will enable us to manage Node.js versions easily.

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

Step2: With nvm installed, you can now check the available Node.js versions:

nvm ls-remote

Step3: Now you will install the latest LTS version of Node in this case in 10/2023 it is 20.9:

nvm install 20.09

Step4: Just to be sure, put the installed version as default

nvm alias default 20.9

Step5: Check the Node version:

node -v

Step6: Be happy and nice coding

[sunkanmii]

Yep, it works for Windows. Was on v16.17.0 before, installed the latest version (v20.9.0) from the node.js site and it works!
Thanks!

[GabrielDelight]

[Fixed] Just update your node js version

nodejs -v // version 16 😢
sudo npm install -g n // Install the n package
sudo n lts // Update to lts version
nodejs -v // version 20 😄

[monkeyK1n9]

This worked for me. Thanks.

I am on a Mac M1
Checking my node version:node -v , I was at v16.20.1, I then upgraded my node version using nvm to the LTS version.
nvm install --lts. At the moment of writing this comment, I am now at v20.9.0.

Everything works now fine.

[GabrielDelight]

I'm glad my answer was able to help xd

[pedrotomas50]

Its works but the old projects doesnt run dev.

[jvmhonorato]

go to package.json file in ur old project and update the NODE. exp: "node":"16.0.9" to "node":"20.0.9", afterwards type "npm install" on terminal.

[vktechturbine]

i face with same problem i have solution
first check current node version in your system
then first update to latest node version using this command
in terminal and type =>
1. node -v => check node version
2. nvm ls-remote -> is in list to check latest node version copy version number v20.0.0
3. nvm ls => is use to how many version you have in your system(optional)
4. nvm install v20.9.0 => this command to install latest version in your system
5. nvm use v20.9.0 -> this command is to use to show now ure useing this version
6. same procedure with your project terminal also then solve the error

[muftisamiullah]

doesnt seems to work for me, On mac, nextjs version 14.0.0 or with 14.0.1, nd tried above solutions.

[ishaanbuildsthings]

This also does not work for me:

TypeError: Cannot convert undefined or null to object

[icyJoseph]

mmmm this can be that for some reason Request, part of the Fetch API family, is not defined for some reason in your environment.

Could you try to create a script (forget about next.js for now), say scripts/index.js and run it with node script/index.js:

const request = new Request("https://www.mozilla.org/favicon.ico");

const url = request.url;
const method = request.method;
const credentials = request.credentials;

console.log({ url, method, credentials })

Does this work for you?

[RomneyDa]

When I ran this script it didn't work, same error

[rameezjafrie]

Many Thanks after updating node version, issue resolved.

[moonRider]

but it works with `sudo`

[moonRider]

I solved this problem by remove NODE_OPTIONS.
