Graphql subscriptions with serverless infrastructure

Hi all,

I am implementing graphql subscriptions using apollo server, we have an existing Node express APP, adding graphql APIs to it, I have tries using apollo-server-express package, which worked fine for queries and mutations but inorder to support, I have added a HTTP server and tried to make it work in serverless by serverless(httpServer), but it is throwing un supported framework error. I also tried “apollo-server-lambda” package, which seems not supporting subscriptions.

Help me how can I implement graphql subscriptions and deploy it in lambda function.
