AttributeError: 'Meta' object has no attribute 'track_seen'

Hi there, recently i’m update from v7 to v10 and everything is working fine until i want open an any existing document this error will show up. but doesn’t had any problem when creating any new document…

Traceback (most recent call last):
File “/home/frappe/frappe-bench/apps/frappe/frappe/”, line 62, in application
response = frappe.handler.handle()
File “/home/frappe/frappe-bench/apps/frappe/frappe/”, line 22, in handle
data = execute_cmd(cmd)
File “/home/frappe/frappe-bench/apps/frappe/frappe/”, line 53, in execute_cmd
return, **frappe.form_dict)

File “/home/frappe/frappe-bench/apps/frappe/frappe/model/”, line 1119, in add_seen
