Hello,
it looks like records are not supported:

public record TestRecord(String name) {
}

Fixed in leangen/graphql-spqr#425, must be merged and used in this project.

Records are partially supported out of the box. When used as output types, records should work fine. As inputs, support is not yet there.

Make sure you're using the latest SPQR version.
Remember that you can always provide custom ResolverBuilder and/or InputFieldBuilder (or even a custom TypeMapper) to add support for any type.

Future versions will include full record type support. But, if you end up implementing it yourself, please so kind to contribute it back.
