Silverstripe 4 tinyMCE not working - silverstripe

Question

Just installed SS4 via composer, everything seems to be working fine on my local machine but the WYSIWYG editor doesn't seem to be working, getting a load of console errors referring to tinyMCE and the vendor.js and webpack.
I am using webpack as a compiler but can't figure out why its not working.
Any help would be appreciated.

Answer 1

Is this on windows?
If so this might be because of the web.config in:
public\assets
Telling your server to redirect all non listed extensions to -> 404
Which does not include .js aka the tinyMce file will give a 404.
Solution: include the .js extension.
