I followed the instructions in the tutorial and I get 500 error (Internal Server Error). Here are the request and the reply:

GET /v1/weatherapikey/forecastrss?w=12797282 HTTP/1.1

X-Target-URI: http://isginnov-test.apigee.net
Connection: Keep-Alive
apikey: sopYQ2cG3LjnoEO3bxRBWQcjsG0HOQyH

HTTP/1.1 500 Internal Server Error
Content-Length: 95
Content-Type: application/json

{
"fault": {
"faultstring": "NullPointerException",
"detail": {
"errorcode": "Internal Server Error"
}
}
}

What could be the problem?

Thanks.
