Check the route ...

void fromwire_route_hop(const u8 **pptr, size_t *max, struct route_hop *entry)
{
    fromwire_pubkey(pptr, max, &entry->nodeid);
    fromwire_short_channel_id(pptr, max, &entry->channel_id);
    entry->amount = fromwire_u32(pptr, max);
    entry->delay = fromwire_u32(pptr, max);
}
