Registering the DateTime Scalar from the Extended Scalars library throwing error #3679

I have recently upgraded my project to using the most recent version of Spring Boot v3.3.2, coming from v3.2.8, and it appears that starting with Spring Boot v3.3.x it is now using the GraphQL Java library v22. I'm also using the GraphQl Java Extended Scalars dependency, and am trying to register the DateTime Scalar.

Everything works and compiles and runs fine in Spring Boot v3.2.8, however, v3.3.2 is throwing the following error at startup:

This is the code where I am registering the DateTime Scalar:

/**
 * The GraphQLConfiguration class is responsible for configuring GraphQL for the application.
 */
@Configuration
public class GraphQLConfiguration {
//----------------------------------------
// Beans
//----------------------------------------

    /**
     * This method returns a RuntimeWiringConfigurer instance that configures the runtime wiring for the GraphQL
     * application.
     *
     * @return A RuntimeWiringConfigurer object that configures the runtime wiring.
     */
    @Bean
    public RuntimeWiringConfigurer runtimeWiringConfigurer() {
        return wiringBuilder -> wiringBuilder.scalar(ExtendedScalars.DateTime);
    }
}

It definitely seems to be coming from this RuntimeWiringConfigurer, because if I remove that, the application starts just fine with no exceptions. I have scoured the forums and documentation looking to see if there is a different way to register Scalars since v22 but everything seem to point to doing it the way I have it.

Thanks in advance for any suggestions!

I would suggest creating an issue against the actual project throwing this exception: https://github.com/spring-projects/spring-graphql/issues

I don't think graphql-java is responsible here.

So after much commenting and restarting, I believe I have finally figured out the problem (hint: It had nothing to do with the DateTime extended Scalar).

I'm not sure what changed from v3.2.8 -> v3.3.x in Spring Boot, but the error is happening around Boolean fields for classes and the supporting graphqls schema files.

The way I had it currently working in v3.2.8 was something like the following:

@Entity
public class Account extends SoftDeleteEntity {
//----------------------------------------
// Member Variables
//----------------------------------------

    /**
     * Single Values
     */

    private boolean isActive;

//----------------------------------------
// Getter Methods
//----------------------------------------

    /**
     * Returns the value of the isActive flag for the Account.
     *
     * @return true if the Account is active, false otherwise
     */
    public boolean isActive() {
        return this.isActive;
    }

//----------------------------------------
// Setter Methods
//----------------------------------------

    /**
     * Sets the boolean flag to indicate if the Account is active or not.
     *
     * @param isActive the boolean value indicating if the Account is active
     */
    public void setIsActive(boolean isActive) {
        this.isActive = isActive;
    }

And the account.graphqls was as follows:

type Account {
    isActive: Boolean
}

Apparently either Spring Boot of GraphQL wants either the account.graphsqls too look like this:

type Account {
    active: Boolean
}

Or it wants me to change my getter method in Account.java to getIsActive() instead of isActive()

I've looked around in changelogs, but I'm not seeing what changed that would make this behave like this?
