#7314 f246ddb71 Thanks @trevor-scheer! - Add an __identity property to HeaderMap class to disallow standard Maps (in TypeScript).
This ensures that typechecking occurs on fields which are declared to accept a
HeaderMap (notably, the httpGraphQLRequest.headers option to
ApolloServer.executeHTTPGraphQLRequest and the http.headers option to
ApolloServer.executeOperation). This might be a breaking change for
integration authors, but should be easily fixed by switching from new Map<string, string>() to new HeaderMap().
#7326 e25cb58ff Thanks @trevor-scheer! - Pin node-abort-controller version to avoid breaking change. Apollo Server users can enter a broken state if they update their package-lock.json due to a breaking change in a minor release of the mentioned package.
