Fix Bug for Odoo Website Theme

My Odoo site runs on a custom OWL-based theme and everything works until I try to update or add a section through the Website Builder. The moment I hit “Save” I get an error and the page refuses to render, so the issue is clearly a functionality error during the section-update process; layout and performance remain normal. I need someone to trace the source of this crash—whether it sits in the OWL components, QWeb templates, or the Python controller—and patch it so that any section can be edited and saved without throwing an exception. Please keep the existing design and custom code intact; the fix should be clean, well-commented, and upgrade-safe. Deliverables • Working theme with the error fully resolved • A brief summary of what caused the bug and what files you modified Acceptance criteria 1. I can add, edit, or delete any section from the Website Builder and save changes without errors. 2. All pages still display exactly as before your intervention. 3. No new warnings appear in the server log. Familiarity with Odoo’s Website module, OWL components, and typical traceback debugging is essential so the job can be finished quickly and correctly.
