When I use one of the following commands,

php bin/magento module:status
php bin/magento setup:upgrade
php bin/magento module:enable <module_name>

I'll get an error

 [Magento\Framework\Exception\SessionException]                       
  Area code not set: Area code must be set before starting a session.

And if I add -vvv option to the command, I'll get the below Exception trace, but I'm not able to find out which file cause the error. Can someone please help?
