Greetings,

I have purchased xf_dashboard and xf_dashboard_hr plugin for my odoo v15 community edition. But unable to install xf_dashboard_hr plugin , below is the error message . Any idea how to fix this issue.

RPC_ERROR
Odoo Server Error
Traceback (most recent call last):
  File "/openhrms/openhrms-server/odoo/api.py", line 886, in get
    return field_cache[record._ids[0]]
KeyError: 1

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/openhrms/openhrms-server/odoo/fields.py", line 1057, in __get__
    value = env.cache.get(record, self)
  File "/openhrms/openhrms-server/odoo/api.py", line 889, in get
    raise CacheMiss(record, field)
odoo.exceptions.CacheMiss: 'hr.employee(1,).announcement_count'

The above exception was the direct cause of the following exception:
