More than one validator was found for the request dto [Project.Request]. Specify the exact validator to register using the Validator() method in endpoint configuration.

Though I've explicitly mentioned the validator in my Endpoint, I still see this error in 5.7.0

CreateEndpoint.cs
public override void Configure() { Verbs(Http.POST); Routes("/streaming"); AllowAnonymous(); Description( req => req .Accepts<Request>("application/json") .Produces((int)HttpStatusCode.Accepted) .Produces<ErrorResponse>((int)HttpStatusCode.BadRequest, "application/json+problem") .Produces<ErrorResponse>((int)HttpStatusCode.NotFound, "application/json+problem"), clearDefaults: true ); Validator<CreateRequestValidator>(); }

UpdateEndpoint.cs
public override void Configure() { Verbs(Http.PATCH); Routes("/streaming"); AllowAnonymous(); Description( req => req .Accepts<Request>("application/json") .Produces((int)HttpStatusCode.Accepted) .Produces<ErrorResponse>((int)HttpStatusCode.BadRequest, "application/json+problem") .Produces<ErrorResponse>((int)HttpStatusCode.NotFound, "application/json+problem"), clearDefaults: true ); Validator<UpdateRequestValidator>(); }

`public class CreateStreamingDrupalAssetsRequestValidator : Validator
{
public CreateRequestValidator()
{
RuleFor(req => req.Doc.Name)
.NotNull()
.NotEmpty()
.WithMessage("Name is required");
}
}

public class UpdateRequestValidator : CreateRequestValidator
{
public UpdateStreamingDrupalAssetsRequestValidator() : base()
{
RuleFor(req => req.Doc.Uuid)
.NotNull()
.NotEmpty()
.WithMessage("UUID is required");
}
}`

pls upgrade to 5.7.2.12-beta
and do validator inheritance like shown below:

public class Update : Endpoint<Request>
{
    public override void Configure()
    {
        Post("/streaming");
        AllowAnonymous();
        Description(x => x
            .ProducesProblemFE(400)
            .ProducesProblemFE(404));
        Validator<UpdateRequestValidator>();
    }

    public override async Task HandleAsync(Request req, CancellationToken ct)
    {
        await SendAsync(req);
    }
}

public class CreateRequestValidator : Validator<Request>
{
    public CreateRequestValidator()
    {
        RuleFor(req => req.Doc.Name)
            .NotEmpty().WithMessage("Name is required");
    }
}

public class UpdateRequestValidator : Validator<Request>
{
    public UpdateRequestValidator()
    {
        Include(new CreateRequestValidator()); //this is how you inherit rules written in other validators
        RuleFor(req => req.Doc.Uuid)
            .NotEmpty().WithMessage("UUID is required");
    }
}
