Answer questions andrewiankidd

Just for the record, I encountered this because I wasn't serializing the whole subscription object, the param hint for Subscription::create suggests you only need a subsect of the fields ( endpoint, publicKey, authToken, contentEncoding)

I noticed chrome was sending a "keys" array which is parsed in Subscription::create and I was missing that, once I passed that through it started working.

useful!
