In my project, i use lumen 5.8(I create my project by "lumen new test" command ). And i use validation's(Illuminate\Support\Facades\Validator) required_without to validate my request parameters. But "required_without " didnot work correctly.

`$fields = [ 'Field_1' => 'required_without: Field_2 | int', 'Field_2' => 'required_without: Field_1 | int', ];

$validator = Validator::make($args, $fields); if ($validator->fails()) { echo "Validate parameters fail. [Error] " . json_encode($validator->errors()) . "\n"; }`

1、if request data is： { "Field_1": 1 }

--actually reuslt: "Validate parameters fail. [Error] {"Field_2":["The field 2 field is required when field 1 is not present."]}

--expected reuslt: no error, because Field_1 field is set to 1, Field_2 is no need to be set.

2、if request data is： { "Field_2": 2 }

--actually reuslt: Validate parameters fail. [Error] {"Field_1":["The field 1 field is required when field 2 is not present."]}

--expected reuslt: no error

3、if request data is： { "Field_1": 1, "Field_2": 2 }

--actually reuslt: no error

--expected reuslt: no error
