FluentValidation MustAsync子节点丢失父属性值

Question

In the parent validator, we have multiple child validations. Declared like this

            RuleFor(x => x.Country)
            .Cascade(CascadeMode.StopOnFirstFailure)
            .NotEmpty().WithMessage(ValidationErrorMessageCodes.CountryRequired)
            .SetValidator(new CountryValidator(countryService)).WithMessage(ValidationErrorMessageCodes.CountryDoesNotExist);

In the CountryValidator we set this

            RuleFor(c => c)
            .MustAsync(async candidateCountryCode =>
                (await countryService.GetAll())
                .Any(x => string.Equals(x.Code, candidateCountryCode, StringComparison.CurrentCultureIgnoreCase)))
            .WithMessage(ValidationErrorMessageCodes.CountryDoesNotExist);

This all worked fine when we used to use Validate and Must, but now we are using ValidateAsync and MustAsync in order to satisfy calls deeper in the Api all using async Tasks.

Since changing it this way we get the following error message

Property name could not be automatically determined for expression c => c. Please specify either a custom property name by calling 'WithName'.

If I add .WithName("Country") to the child Validator, then the parameterName returned is "Country.Country" where it used to be just "Country".

Both inherit from AbstractValidator the parent having a RequestModel and the child just being .

What can I do to just get back to the "Country" error ?
