How to use objectMapper.readValue with records?

Question

I have something like this in my unit test controller:

AppointmentDTO[] getAppointmentResult = objectMapper.readValue(result.getResponse().getContentAsString(), AppointmentDTO[].class);

AppointmentDTO:

public record AppointmentDTO(ProcessingCentre branchName, ProcessingCentre branchId, LocalDate firstAvailableDate) {
    public AppointmentDTO(ProcessingCentre branchName, LocalDate startDate, Integer noDaysAhead) {
        this(branchName, branchName, RandomDateGenerator.randomDateGenerator(startDate,noDaysAhead));
    }
}

But there seems to be a problem with how the mapping is done. I'm pretty sure the problem is in AppointmentDTO[].class as it's not a class anymore but rather a record. The error I'm getting is InvalidDefinition

Thanks for your time
