 - When building a custom resolver:
   - Make sure that you return an object with both `values` and `errors` properties. Their default values should be an empty object. For example: `{}`.
   - The keys of the `errors` object should match the `name` values of your fields, but they _must_ be hierarchical rather than a single key for deep errors:
-    `❌ { "participants.1.name": someErr }` will not set or clear properly - instead, use `✅ { "participants": [null, someErr] }` as this is reachable
-    as `errors.participants[1]` - you can still prepare your errors using flat keys, and then use a function like this one from the zod resolver:
+    `❌ { "participants.1.name": someErr }` will not set or clear properly - instead, use `✅ { participants: [null, { name: someErr } ] }` as this is reachable
