There is no scalar implementation for the named 'LocalDateTime' scalar type

Hello. Thank you very much for making this library publicly available. I’m trying to use LocalDateTime for a project and I’m getting a message saying there’s no scalar named LocalDateTime scalar type, as below:

Caused by: graphql.schema.idl.errors.SchemaProblem: errors=[There is no scalar implementation for the named  'LocalDateTime' scalar type]

What I’ve done

Step 1

Added the Maven dependency.

<dependency>
	<groupId>com.zhokhov.graphql</groupId>
	<artifactId>graphql-datetime-spring-boot-starter-webflux</artifactId>
	<version>4.1.0</version>
</dependency>

Step 2

Added scalar LocalDateTime to my .graphqls schema file.

Question

Is there anything I’m missing? I looked through the README and the WebFlux sample project, but couldn’t figure it out. If further data is needed, the pet project I’m working on is publicly available here.

@setchy I’m thinking to publish it with the release of the GraphQL Java Kickstart Spring Boot 13.0.0 version. But I’m not sure when that version will be released.
