New user with problems in tutorial

Enonic version: 6.14.1
OS: Windows 10 (64bit)
Java 1.8.0_131-b11

I am new to enonics and tried the tutorial. Now i get an error while trying to put a country into the hello region (http://xp.readthedocs.io/en/stable/tutorials/my-first-app/add-favorite-country.html Step 6)

Here is the rror:
405 Method not allowed
com.enonic.xp.web.impl.exception.ExceptionMapperImpl.throwIfNeeded(ExceptionMapperImpl.java:43)

I repeated the tutorial from scratch and got the same error.
Didnt find anything in the logs
Anyone can help, what i am doing wrong?

Hi,

And welcome onboard XP!

This error message is typically for when controllers does not export the method it gets requested by. Your page controller (hello-region.js) should have this line close to the top:
exports.get = function(req) {
which makes it listen to get requests. Any typos there will be critical.

Could you post the contents of your hellor-region.js file?
