Hi,

You don’t need to remove and reinstall Odoo to fix this issue. When Odoo is installed using the .deb package, its source files live inside the system’s Python directories, and the installation method has nothing to do with the error you are seeing. The problem isn’t in Odoo itself—it comes from a custom or third-party module that is calling _action_assign(force_qty=...), a parameter that no longer exists in Odoo 19.

The traceback clearly points to the WooCommerce connector module (woo.manual.queue.process.ept). That module was written for an older Odoo version where _action_assign accepted the force_qty argument. Odoo 19 removed that parameter, so the module becomes incompatible. To fix the issue, you must update or modify the WooCommerce connector so it calls _action_assign() without force_qty, or install the updated module version provided by the vendor.

Removing and reinstalling Odoo will not solve this; the incompatible code will still be there afterward. The correct solution is to patch or upgrade the custom module, not the Odoo installation.

Hope this helps
