Major Changes

• #12644 fe2f005 Thanks @jerelmiller! - Replace the result property on ServerError with bodyText. bodyText is set to the raw string body. HttpLink and BatchHttpLink no longer try and parse the response body as JSON when a ServerError is thrown.

• #12644 fe2f005 Thanks @jerelmiller! - More strictly adhere to the GraphQL over HTTP spec. This change adds support for the application/graphql-response+json media type and modifies the behavior of the application/json media type.

  • The client will parse the response as a well-formed GraphQL response when the server encodes content-type using application/graphql-response+json with a non-200 status code.
  • The client will now throw a ServerError when the server encodes content-type using application/json and returns a non-200 status code.
  • The client will now throw a ServerError when the server encodes using any other content-type and returns a non-200 status code.

  NOTE: If you use a testing utility to mock requests in your test, you may experience different behavior than production if your testing utility responds as application/json but your production server responds as application/graphql-response+json. If a content-type header is not set, the client interprets the response as application/json.

• #12644 fe2f005 Thanks @jerelmiller! - Change the default Accept header to application/graphql-response+json,application/json;q=0.9.

• #12644 fe2f005 Thanks @jerelmiller! - HttpLink and BatchHttpLink no longer emit a next notification with the JSON-parsed response body when a well-formed GraphQL response is returned and a ServerError is thrown.
