Uncaught TypeError: Cannot read property 'replace' of null

Sometimes on page load I get this error in the console (in development): Uncaught TypeError: Cannot read property 'replace' of null

This error ultimately causes the extension not to run at all.

Its hard to track down exactly what causes the error because sometimes a refresh causes it to go away, other times it will load fine as expected.. Any thoughts?

Looks like an issue with webpack-dev-server:

If you set the version to 1.14.0 of webpack-dev-server and reinstall/rebuild it works every time without error.
