No scalar implementation for date / datetime

[timpamungkas]

Hi, I'm trying to use date / datetime on the schema, using codegen gradle plugin.
The class is generated, and no compile error.
However, when I run the spring boot app, it failed with message:

***************************
APPLICATION FAILED TO START
***************************

Description:

There are problems with the GraphQL Schema:
	 * There is no scalar implementation for the named  'Date' scalar type
	 * There is no scalar implementation for the named  'DateTime' scalar type

This is my schema (src/main/resources/schema/employee.graphqls).

scalar Date
scalar DateTime

type Query {
    employees: [Employee]
}

type Employee {
    name: String
    birthDate: Date
    joinDateTime: DateTime
}

The build.gradle

plugins {
    id 'org.springframework.boot' version '2.4.5'
    id 'com.netflix.dgs.codegen' version '4.6.0'
    ...   
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.boot:spring-boot-starter'	

    implementation 'com.netflix.graphql.dgs:graphql-dgs-spring-boot-starter:3.11.0'
    ...
}

generateJava {
   schemaPaths = ["${projectDir}/src/main/resources/schema"]
   packageName = 'com.example.graphql.generated'
}

Generated class

public class Employee {
  private String name;

  private LocalDate birthDate;

  private OffsetDateTime joinDateTime;

  ....
}

How to use date / datetime scalar?
Thanks

Have you tried using the graphql-dgs-extended-scalars dependency and associated application yml/properties?

Yes, you are right. Thanks for the help.
Added this dependencies on build.gradle

	implementation(platform('com.netflix.graphql.dgs:graphql-dgs-platform-dependencies:3.12.0'))
	implementation 'com.netflix.graphql.dgs:graphql-dgs-spring-boot-starter'
	implementation 'com.netflix.graphql.dgs:graphql-dgs-extended-scalars'
