Correct way to map unions in a large schema?

[atkinsj]

I'm ingesting data from censys.io. Their schema is ~10,000 lines long and contains quite a few unions both in terms of arrays and in the form of "type" : [ "null", "long" ],.

What's the correct way to map these types? avrogen generates code that doesn't unmarshal which I don't think is unexpected but I'm not sure the best way to approach this.

Schema is attached. avrogen generated this:

type Root struct {
	IP               *string               `avro:"ip"`
	Location         *RootLocation         `avro:"location"`
	AutonomousSystem *RootAutonomousSystem `avro:"autonomous_system"`
	Whois            *RootWhois            `avro:"whois"`
	DNS              *RootDNS              `avro:"dns"`
	Services         []RootServices        `avro:"services"`
}

which fails to parse with IP: avro: decode union type: unknown union type. My understanding is that *string should be a nullable type and so it shouldn't need to be registered but it seems like it does?

It should decode without registration. Can you provide a small concrete example code snippet of the bug. Then I can drill down into it.

I imagine the issue is here:
