Function Returns Union of Effects Instead of Merging Error and Success Channels

typescript 
const extractFieldsFromEmailAddress = (email: string) => {
  const address = email.split("@")[0]
  const fields = address.split(".")
  if (fields.length !== 3) {
    return Effect.fail(new Error())
  }

  const [model, model_item_id, token] = fields
  return Effect.succeed({ model, model_item_id, token })
}

typescript 
const extractFieldsFromEmailAddress: (email: string) => Effect.Effect<never, Error, never> | Effect.Effect<{
    model: string;
    model_item_id: string;
    token: string;
}, never, never>
