Hello everyone,

Can you help me with this error: 

AttributeError: 'crm.lead' object has no attribute '_is_notification_scheduled'

It appears when I want to create CRM lead record, SALE record, or HELPDESK record.

I am using Odoo 17 Enterprise version.

Class MailThread with method _notify_thread with using self._is_notification_scheduled. This class inherit "mail.thread" which has def _is_notification_scheduled. Also I checked the  module Lead ("crm.lead") to see that it inherits "mail thread cc" 

​

Lead with inherit "mail.thread.cc" (I tried to inherit "mail.thread" but doesn't see this module)

Error in CRM:

File "/home/zerus/odoo-17.0/odoo/addons/mail/models/mail_thread py", line 2175, in message_post

    self._notify_thread(new_message, msg_values, **notif_kwargs)

  File "/home/zerus/odoo-17.0/enterprise/mail_mobile/models/mail_thread py", line 25, in _notify_thread

    scheduled_date = self._is_notification_scheduled(kwargs.get('scheduled_date'))

                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
