Location of PHP error logs in Laravel Homestead

I'm currently experiencing routing issues, where various pages of my application are returning white pages.

Where are the PHP logs located within Homestead Vagrant so I can diagnose what's the issue?

I've checked /var/log/ and I can only see a php7.0-fpm.log that relates to PHP, but nothing is generated within here when I read it.
