I have created my Own custom report in which when I print my report at that time the below error message will be created
500: Internal Server Error
I don't know where I should start with the problem solution. The log file in /var/log/odoo/ says:
and my log file /var/log/odoo/
"MissingError: ('MissingError', u'One of the documents you are trying to access has been deleted, please try again after refreshing.')"
Do you have any solution to resolve this problem ?.
Try Running odoo.py when such error occur. It will show where exactly the error occurred. After you fix all the issues under odoo.py. You are good to go.
