Overcoming Unexpected Token Error while Deploying Next.js App on GCP with Node.js 18.13.0

Overcoming Unexpected Token Error Deploying Next.js App on GCP with Node.js 18.13.0

In this article, we will discuss how to resolve the "Unexpected Token" error that occurred while deploying a Next.js app on Google Cloud Platform (GCP) using Node.js version 18.13.0. We will cover key concepts and provide detailed context on the topic. The article will be at least 800 words long and will include subtitles, paragraphs, code blocks, and a summary with references in an unordered list.

Introduction

Next.js is a popular JavaScript framework for building server-side rendered (SSR) applications. Google Cloud Platform (GCP) is a cloud computing service that offers a variety of services such as computing, data storage, and networking. Node.js is a JavaScript runtime that allows you to run JavaScript on the server-side. In this article, we will discuss how to resolve the "Unexpected Token" error that occurred while deploying a Next.js app on GCP using Node.js version 18.13.0.

The Problem

While deploying a Next.js app on GCP using Node.js version 18.13.0, an "Unexpected Token" error occurred. The error was caused by the use of the nullish coalescing operator (??) which is a new feature introduced in Node.js version 14.0.0.

Solution

To resolve the "Unexpected Token" error, you need to downgrade the Node.js version to a version that supports the nullish coalescing operator. In this case, you can downgrade to Node.js version 14.0.0 or later.

Step 1: Check the Current Node.js Version

To check the current Node.js version, run the following command:

Step 2: Install a Supported Version of Node.js

To install a supported version of Node.js, you can use a version manager such as nvm or nvm-windows.

Using nvm

To install Node.js version 14.0.0 using nvm, run the following command:

Using nvm-windows

To install Node.js version 14.0.0 using nvm-windows, run the following command:

Step 3: Switch to the Supported Node.js Version

After installing the supported version of Node.js, you need to switch to it. To switch to Node.js version 14.0.0, run the following command:

Step 4: Verify the Node.js Version

To verify that you are using Node.js version 14.0.0, run the following command:

Step 5: Redeploy the Next.js App

After switching to a supported version of Node.js, redeploy the Next.js app. The "Unexpected Token" error should no longer occur.
