I Can’t Load JS on Odoo 17: A Step-by-Step Guide to Solving the Issue

Are you tired of seeing that frustrating error message “Failed to load resource: the server responded with a status of 404” or “Uncaught Error: Cannot find module” when trying to load JavaScript files on Odoo 17? You’re not alone! In this article, we’ll take you by the hand and walk you through the troubleshooting process to resolve the “I can’t load JS on Odoo 17” issue.

Understanding the Problem

Before we dive into the solutions, it’s essential to understand the root cause of the problem. Odoo 17 introduced significant changes to the way JavaScript files are loaded, which can cause issues with custom modules or third-party libraries. Here are some common reasons why you might encounter this problem:

• Incorrectly configured __manifest__.py file
• Missing or incorrectly defined JavaScript files in the module
• Incompatible JavaScript libraries or dependencies
• Odoo 17’s new JavaScript architecture

Step 1: Verify the __manifest__.py File

The __manifest__.py file is the heart of your Odoo module, and its incorrect configuration can lead to JS loading issues. Let’s review the essential elements:

{
    'name': 'My Module',
    'version': '1.0',
    'author': 'Your Name',
    'description': 'My Module Description',
    'depends': ['base'],
    'data': [
        'views/my_view.xml',
        'static/src/js/my_script.js',
    ],
    'installable': True,
    'application': True,
    'auto_install': False,
}

Make sure you have the following:

• A valid name and version
• The correct depends list, including any necessary modules
• The data list, which includes the path to your JavaScript file(s)

Step 2: Inspect the JavaScript File(s)

Next, let’s examine the JavaScript file(s) themselves. Ensure that:

• The file(s) are correctly defined in the data list of the __manifest__.py file
• The file(s) are located in the correct directory (e.g., static/src/js/)
• The file(s) have the correct syntax and are properly formatted

Here’s an example of a basic JavaScript file:

odoo.define('my_module.my_script', function(require) {
    "use strict";
    console.log("My script is loaded!");
});

Step 3: Check for Incompatible Libraries or Dependencies

With the rise of Odoo 17, some older libraries or dependencies might not be compatible with the new JavaScript architecture. Check if you’re using any outdated or incompatible libraries:

• Verify the library’s compatibility with Odoo 17
• Check if the library has been updated for Odoo 17
• Consider using alternative libraries or dependencies

Step 4: Understand Odoo 17’s New JavaScript Architecture

Odoo 17 introduced significant changes to the JavaScript architecture, which can affect how custom modules are loaded. Familiarize yourself with the new architecture:

Odoo 17 uses a modular architecture, where each module is a separate application. This means that each module has its own JavaScript scope, and modules can’t access each other’s JavaScript files directly.

Here’s a brief overview of the new architecture:

Module	JavaScript Scope
Base Module	Global scope
Custom Module	Module scope (isolated from other modules)

Step 5: Debug and Troubleshoot

By now, you should have resolved the issue, but if you’re still facing problems, it’s time to debug and troubleshoot:

1. Check the browser console for any error messages
2. Verify that the JavaScript file is being loaded correctly
3. Use the Odoo debugger to step through the code
4. Consult the Odoo community forums or online resources for similar issues

Conclusion

Loading JavaScript files on Odoo 17 can be challenging, but by following these steps, you should be able to resolve the “I can’t load JS on Odoo 17” issue. Remember to:

• Verify the __manifest__.py file configuration
• Inspect the JavaScript file(s) and their paths
• Check for incompatible libraries or dependencies
• Understand Odoo 17’s new JavaScript architecture
• Debug and troubleshoot any remaining issues

With patience and persistence, you’ll be able to overcome this hurdle and create powerful, JavaScript-driven Odoo modules.
