Fix SerovalMissingReferenceError

✅ Solution

The "SerovalMissingReferenceError" in Clerk often arises when serializing complex objects, particularly user metadata, that contain circular references or unserializable data types like functions or symbols. To fix this, ensure your public and private metadata only contain primitive data types (strings, numbers, booleans) or serializable objects. Consider using a custom serialization function (like `JSON.stringify` with a replacer) to prune or transform the metadata before passing it to Clerk functions like `getAuth` or user update methods.
