Magento – Magento 2.1 Uncaught TypeError: Cannot read property ‘replace’ of null

Hi whenever I try to create a new product I get the following error in the console:

Uncaught TypeError: Cannot read property 'replace' of null

This is the only time I get this, I can create pages, blocks etc. But not the products. It looks like It doesn't generate the static-content correctly for some reason.

I'm running my installation on Forge with nginx, php7.0 and mysql5.7.12-0ubuntu1.1 and Ubuntu 16.04.

The full error log is:
