With the necessary update to Spring 7, the already deprecated usage of MediaType#APPLICATION_GRAPHQL was removed in Spring 7, thus can’t be used anymore. The recommended replacement is MediaType#APPLICATION_GRAPHQL_RESPONSE.

Since the different media type values are used for the HTTP content type header, this means, that clients cannot use the old value application/graphql+json anymore. Uses application/graphql-response+json instead!

If you’re using application/graphql-response+json already, you don’t need to change anything and might consider this as non-breaking.
