Hi,

This is a great library! I'm trying to get the Jeopardy example up and running.

What I've done

  1. Set up an alexa skills w/ intents + utterances
  2. Run the skillserver example by running go build inside of the jeopardy directory
  3. Attempt to send a test to my endpoint, with the phrase "start a game"

I get the following stacktrace from the ./jeopardy program:

[negroni] PANIC: interface conversion: interface {} is nil, not *skillserver.EchoRequest

Has anyone seen this before?

How are you sending the request to your endpoint? Is it through the Alexa request simulator? If it isn’t properly formatted it may not be able to decide it into an EchoRequest if is is missing fields.

I'm sending the request to my endpoint via the Alexa request simulator. it looks like this:

Closing this issue - the problem was the the jeopardy.go examples still relied on github.com/gorilla/context rather than the native GoLang context. Cheers!

Is that a change that should be merged in so others don't run into this issue? Glad you got it figured out.
