Fixing Chrome Extension Manifest Errors: How to Resolve Common JSON Issues

Creating a Chrome extension can be an exciting project, but encountering errors in your manifest file can be incredibly frustrating. If you've been hit with issues like "Trailing comma not allowed" or "Dictionary keys must be quoted," you're not alone. In this guide, we'll break down these problems and provide clear steps to effectively resolve them.

The Problem at a Glance

Upon trying to change the icon of your Chrome extension, you might have encountered the following two common errors in your manifest file:

Dictionary keys must be quoted: This error typically occurs when the keys in a dictionary (or object) definition are not properly enclosed in quotes.

Trailing comma not allowed: This error arises when there is an unnecessary comma after the last item in a list or a set of key-value pairs.

In Chrome extensions, the manifest file (usually named manifest.json) is where all necessary metadata and configurations sit. For example, it specifies the extension's name, version, descriptions, icons, and permissions.
