As the doc says: "By default in no debug mode all errors will be logged and replace by a generic error message. Only query parsed error won't be replaced." https://github.com/overblog/GraphQLBundle/blob/f35dda77dd57179f3696b9217f1a383eb86621b5/docs/error-handling/index.md

I'm trying to ensure that on production, the end user never sees any exceptions, only generic error messages. But I don't see a way to do this for query parse errors, like when I request /graphql and get a "Bad Request: Must provide query parameter". How can those exceptions be replaced?
