I am running odoo version 14. and after I log in the following pop up error appears and the  discus or anything else is not displayed. But if I then click on something, like invoicing it all seems to be Ok. My question is what is the following error and how can I resolve it. This is the error which appears.  thanks.

Traceback (most recent call last):
  File "C:\erP\server\odoo\addons\web\controllers\main.py", line 2112, in report_download
    data = dict(url_decode(url.split('?')[1]).items())  # decoding the args represented in JSON
