## Notes

<Warning>
  `summary` is a stringified JSON string, not a nested object. You must call `JSON.parse(catalystEvent.summary)` before accessing fields like `city` or `deceasedName`. See [CatalystSummary](/types/catalyst-summary) for the parsed shape.
</Warning>

<Note>
  Additional `type` values beyond `PREPROBATE` may be available depending on your account configuration. Contact your Goliath account manager for the full list.
