Warning: never upgrade nodebb without taking a back-up of your working code.

The release process, tests etc are yet to mature. (18th Jan 2018)

Error:

TypeError: Path must be a string

The stack trace did not point to any file in the development project but in the node_modules (dependancy stack):

TypeError: Path must be a string. Received undefined     at assertPath (path.js:28:11)

Got to know that problem lies in the browserlist package:

https://github.com/ai/browserslist/issues/158

https://github.com/postcss/autoprefixer/issues/865

But !

Browserlist was not a direct dependancy: (npm ls | grep borwser)

It was used in: autoprefix

So, used a version of autoprefixer that uses a version of borwserify where this was fixed.

Finally this fixed it:
