If you’ve encountered the error message: “The message port closed before a response was received” while developing or testing a Chrome extension, you’re not alone. This error can be perplexing, but it’s often related to issues with Chrome extensions. Let’s explore the potential causes and solutions to this problem.
Understanding the Error
This error typically arises when a promise in your Chrome extension’s code does not receive a response. It often occurs when an extension is improperly handling asynchronous operations, leading to unhandled promise rejections.
Common Causes and Solutions
1. Extension Conflicts
The most common cause of this error is conflicts between different Chrome extensions. Here are some steps to identify and resolve these conflicts:
- Disable all extensions by navigating to
chrome://extensions/or through Settings > Extensions. - Enable extensions one by one to identify the problematic extension.
Extensions such as Wappalyzer, Katalon Recorder, and others have been reported to cause this issue. Once identified, you can either update or temporarily disable the extension until a fix is available.
2. Specific Extension Issues
If you’re using the Wappalyzer extension, updating to version 4.0.1 or later may resolve the issue. You can reinstall it from the
Chrome Web Store.
For other extensions like Katalon Recorder, ensure you’re using the latest version, or consider alternative tools if the issue persists.
Using Repeato for Test Automation
If you frequently encounter testing issues with Chrome extensions and need a robust solution, consider using Repeato. As a no-code test automation tool, Repeato simplifies the process of creating, running, and maintaining automated tests for web applications. It leverages computer vision and AI to streamline testing, making it a practical alternative to tools like Katalon, which can sometimes fall short due to scripting limitations and resource demands.
Repeato supports both data-driven and keyword-driven testing, and its ability to run command line scripts or JavaScript code makes it highly adaptable. All tests and workspace data are saved in text and JSON formats, ensuring easy version control and collaboration within your team.
