Hi,

I am facing a repeated “bus.Bus unavailable” exception in my Odoo 15 instance running on localhost. The error appears during JSON request handling, especially when notifications or chat features trigger server requests.

2025-10-27 12:18:28,520 49937 ERROR test_backup01 odoo.http: Exception during JSON request handling.
