The return from agent.getProfile fails AppBskyActorProfile.isRecord()

[OracPrime]

If I call
const data=agent.getProfile({ actor: agent.did });
Then I expect this call to return true
AppBskyActorProfile.isRecord(data)

It doesn't. data contains the fields you would expect, but the code generated for isRecord expects a type$ member:

export function isRecord(v: unknown): v is Record {
  return (
    isObj(v) &&
    hasProp(v, '$type') &&
    (v.$type === 'app.bsky.actor.profile#main' ||
      v.$type === 'app.bsky.actor.profile')
  )
}

Note: I'm new to atproto development - give serious consideration to me having just missed the point!
