Hi! Thanks for trying out the library, sorry you had issues with one of the samples. I've replicated and fixed the issue which is now published here on Github. Please try it now and open another issue if it still doesn't work.

@matthewayne Would you mind elaborating on the cause and the fix please? I am getting exact same error for my own example. Thanks.

@matthewayne: We're getting the same issue - proposed fix in #51 - please review...

It is very hard to debug cloud functions. What am i doing wrong?
Here is the fulfillment request:
