no registration found for type `{}`

Error message

no registration found for type `{}`

What it means

Panic in TypedReflectDeserializer::of: the requested type T has no registration in the supplied TypeRegistry. Register T (registry.register::<T>()) before constructing this deserializer, or use the registration-taking constructor.
