CustomValidator is not being called during manual call - spring

Question

I have the following CustomValidator and Annotation that work fine when I call it as part of endpoint parameter check (run() method in service). I'd like to call the same validator manually in method run2(), but during execution of the endpoint my custom validator is not being called. What am I doing wrong?
Annotation
import javax.validation.Constraint;
import javax.validation.Payload;
import java.lang.annotation.Documented;
import java.lang.annotation.Retention;
import java.lang.annotation.Target;
import static java.lang.annotation.ElementType.*;
import static java.lang.annotation.RetentionPolicy.RUNTIME;
#Target({PARAMETER, FIELD, METHOD, ANNOTATION_TYPE, TYPE_USE})
#Retention(RUNTIME)
#Constraint(validatedBy = {ExecutionRequestValidator.class})
#Documented
public #interface ValidateRequest {
String message() default "{Invalid Request}";
Class<?>[] groups() default { };
Class<? extends Payload>[] payload() default { };
}
Validator (concrete class implements isValid())
import lombok.extern.slf4j.Slf4j;
import org.hibernate.validator.constraintvalidation.HibernateConstraintValidatorContext;
import org.springframework.stereotype.Component;
import javax.validation.ConstraintValidator;
import javax.validation.ConstraintValidatorContext;
import java.lang.annotation.Annotation;
#Component
#Slf4j
public abstract class BaseValidator<A extends Annotation, T> implements ConstraintValidator<A, T> {
protected boolean handleConstraintValidationFailure(
ConstraintValidatorContext context, String message, ValidationErrorCode errorCode) {
if (context != null) {
log.error("BaseValidator#handleConstraintValidationFailure ErrorCode: {}, Message: {}",
errorCode, message);
context.disableDefaultConstraintViolation();
HibernateConstraintValidatorContext hibernateContext =
context.unwrap(HibernateConstraintValidatorContext.class);
// passing error code that will be set as code value in the response
hibernateContext
.withDynamicPayload(errorCode.getId().toString())
.buildConstraintViolationWithTemplate(message)
.addConstraintViolation();
}
return false;
}
#Override
public void initialize(A constraintAnnotation) {
ConstraintValidator.super.initialize(constraintAnnotation);
}
}
