Hi,

The error "TypeError: Cannot read properties of null (reading 'classList')" in web.assets_frontend_lazy.min.js during a manual repository scan in the Odoo App Store indicates that JavaScript is trying to access a property of a missing HTML element. This can be due to a missing or incorrectly loaded element, a timing issue where the JavaScript runs before the element loads, a conflict with a custom module, an Odoo core bug, or a caching problem.

To troubleshoot, first clear your browser cache and hard reload the page. Disable custom modules to check for conflicts. Use browser developer tools to inspect the HTML and look for missing elements or JavaScript errors. Examine Odoo server logs for related errors. Test in a clean Odoo environment if possible. If the issue persists, consider contacting Odoo support.

Hope it helps
