Configure custom ObjectMapper for GraphQL

How can I specify an ObjectMapper that has to be used when calling the /graphql endpoint?

I am using spring boot and the graphql-spring-boot-starter dependency version 7.0.1.

I found github issue: https://github.com/graphql-java-kickstart/graphql-spring-boot/issues/97. Where a combination of ObjectMapperConfigurer and schemaParserOptions is mentioned. However that does not work for me.

I currently have the following JacksonConfig.

@Configuration
public class JacksonConfig {

    @Bean
    public ObjectMapper objectMapper() {
        return new ObjectMapper()
                .setDefaultPropertyInclusion(JsonInclude.Include.NON_EMPTY)
                .findAndRegisterModules();
    }

    @Bean
    ObjectMapperConfigurer objectMapperConfigurer() {
        return (mapper, context) -> mapper.setDefaultPropertyInclusion(JsonInclude.Include.NON_NULL);
    }

    @Bean
    SchemaParserOptions schemaParserOptions() {
        return SchemaParserOptions.newOptions()
            .objectMapperConfigurer((ObjectMapper mapper, ObjectMapperConfigurerContext context) -> mapper.setDefaultPropertyInclusion(JsonInclude.Include.NON_NULL))
            .build();
    }
}

As you can see I am trying to set a different setting for DefaultPropertyInclusion when calling the \graphql endpoint. (This is because I want the empty interfaces: [] array to be in the response from the introspection)

However, currently with the above configuration, the ObjectMapper with DefaultPropertyInclusion = NON_EMPTY is still being used when doing the graphql introspection. Instead of the ObjectMapper with DefaultPropertyInclusion = NON_NULL.

Can you help me with how I should configure a custom ObjectMapper for the queries on /graphql?
