Im trying to build a graphql schema during runtime without any static schema definitions. I have the following classes

@Component
public class GraphQLProvider {

    private GraphQL graphQL;

    private final ConnectionManager connectionManager;

    public GraphQLProvider(ConnectionManager connectionManager) {this.connectionManager = connectionManager;}

    @PostConstruct
    public void init() {
        GraphQLSchema schema = buildSchema();

        System.out.println( new SchemaPrinter().print( schema ) );

        this.graphQL = GraphQL.newGraphQL( schema ).build();
    }

    public GraphQL getGraphQL() {
        return graphQL;
    }

 private GraphQLSchema buildSchema() {
        GraphQLObjectType queryType = GraphQLObjectType.newObject().name( "Query" )
            .field( field -> field
                .name( "hello" )
                .type( Scalars.GraphQLString )
                .dataFetcher( environment -> "world" ) )
            .build();

        return GraphQLSchema.newSchema().query( queryType ).build();
    }

}

@Configuration
public class GraphQLConfig {

    @Bean
    @Primary
    public GraphQlSource graphQlSource(GraphQLProvider graphQLProvider) {
        GraphQLSchema schema = graphQLProvider.getGraphQL().getGraphQLSchema();
        return GraphQlSource.builder( schema ).build();
    }
}

The schema printed by schemaprinter is expected and its correct.

I experience 404 when I try to query with this setup in postman but if i run with predefined graphql schemas without the dynamic generation i get the result as expected.

The error

I don't want to any static files in my resources rather to be initialized in runtime.
