What is the current behavior?
I followed the instructions on the angular-cli wiki to use universal, all compiled correctly with no errors.
The Universal App fails on
http://localhost:4200the first time it loads but works onhttp://localhost:4200/index.htmlIt works fine if I just run a http-server on client folder.
After loading
http://localhost:4200/index.htmlthe first time, thenhttp://localhost:4200is accessible.The error I receive is 500 with a response of :
Which seems to be a server error.
