 ### Error tracking/reporting
 
 To respect the graphql spec, all errors need to be returned as json and `rack-graphql` catches all exceptions and does NOT re-raise them. You can change this behavior via `re_raise_exceptions` argument.
 Because of this, using error tracking middleware (`use Sentry::Rack::CaptureExceptions`, `use Raven::Rack`) does not take any effect for graphql requests.
 
-To use Sentry or other reporting tool for graphql queries, you can use `GraphQL::Schema` middleware:
+To use Sentry or other reporting tool for graphql queries, you should handle it on graphql schema level:
 
 ```ruby
-class GraphqlErrorTrackerMiddleware
-  def self.call(parent_type, parent_object, field_definition, field_args, query_context)
-    yield
-  rescue StandardError => e
+class MySchema < GraphQL::Schema
