Google App Engine : when connecting to http://localhost:8080 get HTTP Error 500 Internal server error

Posted on Updated on

So I was running google app engine in order to get some code running.

at this point there is a prompt to allow updates on running, I said Yes.

At this point the app was running as it should, also when I quit this and went in using the launcher again, that worked too.

Once I ran the command it was able to give me feedback on my code via error messages that  I wasnt getting with GAE. And it’s always something simple….
