string with format: date not working

Hi,

I'm trying to validate requests using request validation middleware. In one of my API, I'm using following rule for one of my query params in API.

{
            "name" : "from_date",
            "in" : "query",
            "schema" : {
              "type" : "string",
              "format" : "date",
              "example" : "2017-09-24"
            }
 }

As per, this rule request should fail if passed value is not a valid date but it's not failing if I pass from_date=abc.

If I update format to date-time and then if I pass from_date=abc then it's giving me error as expected.

Request should fail if format is date and I pass from_date=abc.

Start at the request validation middleware and the schema format handling for query parameters. Reproduce the issue with the provided schema using from_date=abc, then compare the date and date-time paths. Done means an invalid value for format date is rejected with a validation error.
