Custom error message for http 400

[gingerdin]

Hi,

I need to return the custom error message with concrete structure (general structure for the whole application) for the HTTP 400. In case, for example, when the user provided totally wrong request
(e.g. <app_url>/graphql)

Seems that there is no possibility to provide extensions to the graphql.servlet.AbstractGraphQLHttpServlet#AbstractGraphQLHttpServlet(java.util.List<graphql.servlet.GraphQLServletListener>, boolean) for the getHandler

Thanks for any help

@gingerdin We're about to refactor that part so will keep this in mind while doing so.
