The field `notified_partner_ids` has type Many2many with relation table
`mail_message_res_partner_needaction_rel` [1] which is a regular Odoo model
`mail.notification` with some extra fields. One of those fields is required:
`notification_type`.
On copying `mail.message` record, ORM copies Many2many fields directly without
using `default_get` method for `mail.notification` model. Particularly,
`notification_type` get null value and we get an error.
STEPS
1. Create Server Action for `mail.message` model:
```py
for message in (records or record):
message.copy({
"subject": message.subject + "(SA copied)",
})
```
2. Add contextual action
3. Open `mail.message` which has non-empty value on
`notified_partner_ids` (*Partners with Need Action*)
4. Run the Server action via Action menu.
PROBLEM
```
ValueError: <class 'psycopg2.errors.NotNullViolation'>: "null value in column
"notification_type" of relation "mail_notification" violates not-null constraint
DETAIL: Failing row contains (11, 210, null, 3, null, null, null, null, null,
null, null, null, null).
```
SOLUTION
Fix it by adding `copy=False`, because we don't want to copy those values
anyway (confirmed by TDE).
[1]: The relation table is renamed to `mail_notificaiton` in v15+
