# "Objects are not valid as a React child (found: object with keys {<key…" — react 19.0
cause: JSX renders strings, numbers, elements and arrays of them; a plain object or a Date has no rendering, so React throws while reconciling children

arms: works 19.0
risk: low
fix (patch):
~~~
-<p>{user}</p>
+<p>{user.name}</p>
-<time>{createdAt}</time>
+<time>{createdAt.toISOString().slice(0, 10)}</time>
-<ul>{itemsById}</ul>
+<ul>{Object.values(itemsById).map((i) => <li key={i.id}>{i.label}</li>)}</ul>

repro: none
check: none
don't:
