A sample application to demonstrate an issue with parameters validations with spring-graphql 1.1.2

When you run the playground and perform the following mutation you'll see validation errors in the application log:

mutation {
  createCustomerDetails(input:{
    email:"",
    name:"",
    phoneNumber:"",
    locale:"",
    deliveryDetails: null
  }) {
    id
  }
}

When you remove the override for the 1.1.1 version from the build.gradle.kt file, and rely on 1.1.2 provided through the boot started no validation errors are logged, and the application errors on the TODO(..) statement.
