I running a local odoo enterprise instance using docker, I downloaded the odoo enterprise source code and mounted it to my container, it works very well except when I try to install the app Pay to Book on Ecommerce, I get this error:

2025-11-26 11:02:33 2025-11-26 16:02:33,895 1 ERROR odoo odoo.tools.convert: The XML file '/mnt/enterprise/website_appointment/views/snippets/s_appointments.xml' does not fit the required schema!

2025-11-26 11:02:33 AssertionError: Element odoo has extra content: template, line 4


I can download this app fine on my online instance but it breaks on a local instance. Heres my odoo.conf:


[options]
addons_path = /usr/lib/python3/dist-packages/odoo/addons,/mnt/enterprise,/mnt/extra-addons

Heres how I mount with docker:


  web:
    image: odoo:18.0
    depends_on:
      - db
    ports:
      - "8069:8069"
    volumes:
      - odoo-data:/var/lib/odoo
      - ./config:/etc/odoo
      - ./addons:/mnt/extra-addons
      - ./enterprise/odoo/addons:/mnt/enterprise

Hello
Yes it is not good practice to remove the code instead of knowing the root reason of the error but it is okay for local instance working..
If it is possible can you share the code of this file "s_appointments.xml".
Thanks.

Hello,
Better approach: Override or exclude the asset in your custom module's XML:

<delete id="website_appointment.s_online_appointment_000_js"/>
This way your fix survives Odoo updates and stays version-controlled in your module.

Hello Chuck Mako
I hope you are doing well

Your Download is Correct
Mount path ./enterprise/odoo/addons:/mnt/enterprise is fine for downloaded sources.
Real Issue : Version mismatch - verify you downloaded Odoo 18 sources:

head -10 ./enterprise/odoo/addons/website_appointment/__manifest__.py
# Should show 'version': '18.0.x.x.x'

If not 18.0, re-download correct version.

I hope this information helps you

Thanks & Regards,

Thank you for your answer, just to be sure, I got downloads "Sources" for Odoo 18 enterprise here: https://www.odoo.com/page/download

The addons in the download is in this folder: enterprise/odoo/addons when downloading from the link, that's why my mount is like that. Am I downloading the right source?

Also I don't get what you mean by checking the manifest because the manifest states the module version, not the odoo version

There's also the fact that modules like hr work really well, it seems to be only a problem with this module in particular, which is frustrating

I fixed it by deleting
<asset id="website_appointment.s_online_appointment_000_js" name="Appointment Button 000 JS">
<bundle>web.assets_frontend</bundle>
<path>website_appointment/static/src/snippets/s_online_appointment/000.js</path>
</asset>

At the end of the xml files, obviously its not good to modify the source code but since it's local I guess its not so bad
