Unable to parse processed event

[Neonkiller]

Web hook like
{
"sg_event_id": "IVqXzcSwSMqtCBqkfZX5Gw",
"sg_message_id": "DhEasnaCSFC0S316nbnQ8Q.filter0611p1iad2-28144-5AAFA6CF-2B.0",
"send_at": 1521461003.98953,
"event": "processed",
"email": "some@email.com",
"smtp-id": "<xxx.sendgrid.net>",
"timestamp": 1521460944,
"CommunicationId": "7627b608-ea32-45e5-8567-e7cd91e3facc"
},

can not be parsed.
It crashed on parse of "send_at": 1521461003.98953
as it can not handle double values.
Possible fix:

• parse all as double or add additional check for double values
