Encoding an APNs token in JSON for node-apn (parse-server)

I've deployed a parse-server app in Heroku that I'd been developing locally using Docker. This app uses push notifications, and so needs access to some crypto data to play with APNs.

Locally I mounted a volume with the token key file in it. On Heroku this isn't an option, and I don't want to bundle the key in the package unencrypted. I've been trying to encode the token key in the JSON argument to the "PARSE_SERVER_PUSH" environment variable in different ways. It seems what's needed is a Buffer, but I have no idea how to represent such a thing in JSON, and I haven't found anything through some searching.

I'm currently using this at my push config:

{"ios": 
    {
        "token": {
        "key": {"type":"Buffer","data":[45, 45, ... 45]},
        "keyId": "MYKEYID",
        "teamId": "MYTEAMID" 
        },
        "topic": "com.myApp", 
        "production": false
    }
}

But the server chokes on the 'key' field:

Does anybody know how to achieve this?

EDIT: The documentation (https://github.com/node-apn/node-apn/blob/master/doc/provider.markdown) suggests it's possible:

token.key {Buffer|String} The filename of the provider token key (as supplied by Apple) to load from disk, or a Buffer/String containing the key data.
