Hi everyone,

I'm working with Odoo 18 and have added some custom cards to the portal using the following custom modules: `customer_notes_odoo`, `calendar_meeting_portal`, and `contacts_patient`.

The cards were built by replicating the structure used in Odoo core, including both the XML views and the Python controller. However, when I load the portal, I get the following error in the browser console:

UncaughtPromiseError > TypeError

Uncaught Promise > Cannot set properties of null (setting 'textContent')

    at async Promise.all (index 2)

This only happens with the new custom cards. The default cards from Odoo work fine.

Does anyone have an idea of what might be causing this? Could it be that a DOM element expected by the JS isn't found or properly initialized?

Happy to share any additional code or details if needed. Thanks in advance for your help!
