Magento 2 How to throw report error page (500 error) for testing purpose

 The goal is to get a report page for testing purpose 

So, we have to break magento somehow.

The fast way is:

1. pub/media is symlink to media folder

2. rename real media folder to media.bk

3. open PLP and enjoy the error

var/report will be:

Directory \"\/mnt\/data\/www\/project\/releases\/pub\/media\" cannot be created Warning!mkdir(): File exists" ...
