I'm developing a custom module for odoo and suddenly got this error:
Internal Server Error The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
And I don't know how to find the problem I'm using odoo enterprise 14 installed on ubuntu 20 Please I need a way to understand what happen
You can read the status of the odoo service and will tell you the output of the logfile.
Try
sudo service odoo status
or
sudo service odoo-server status
The output will show the location of the log file.
