Can't use "if" condition in a pattern match when defining validator with DSL

[webblin034]

Official Document :
" Accord supports several native Scala control structures, notably ifs and pattern matching "
in http://wix.github.io/accord/dsl.html

Library Dependencies :

libraryDependencies ++= Seq(
  "com.wix"                   %% "accord-core"                 % "0.7.6" % Test,
  "org.scalatest"             %% "scalatest"                   % "3.2.2"  % Test
)

Input Data :

case class InputData(
  id: String,
  name: Option[String] = None,
  description: Option[String] = None,
  items: Seq[String] = Seq.empty
)

Unit Test :

      val data = InputData("", None, None, Seq.empty)
      val result = validate(data)
      result.isFailure shouldBe true
      result.toFailure.value.violations.size shouldBe 4

Compilation Failed !

  implicit val inputDataValidator: Validator[InputData] = validator[InputData] { request =>
    request.name match {
      case None => {
        request.id is notBlank
        if (request.description.isEmpty) {
          request.name.mkString is notBlank
          request.description.mkString is notBlank
        }
        request.items is notEmpty
      }
      case Some(_) =>
    }
    ()
  }

Test Compilation Error :

[error] not found: value request
[error]  if (request.description.isEmpty) {
[error]      ^
[error]  one error found

Test Failed, Shouldn't Ignore All Assertions !

  implicit val inputDataValidator: Validator[InputData] = validator[InputData] { request =>
    request.name match {
      case None => {
        if (request.description.isEmpty) {
          request.id is notBlank
          request.name.mkString is notBlank
          request.description.mkString is notBlank
          request.items is notEmpty
        }
      }
      case Some(_) =>
    }
    ()
  }

you should probably use .each operator,
for example:

request.description.each is notBlank
