/graphql/stream endpoint returning 404 with fastify and useGraphQLSSE plugin

[nickqweaver]

I'm refactoring my application and moving off of express in favor of Fastify. Using express I followed the documentation and was able to successfully get events streamed to the client. Now that I'm on fastify i'm getting a 404 error
"msg":"Route PUT:/graphql/stream not found"}.

Is there something else I need to do to expose the /graphql/stream endpoint to get this to work with fastify?

Could you share a reproduction?

I was able to get this working by explicitly creating a 2nd route for /graphql/stream. Express worked by setting up the single route with yoga.graphqlEndpoint while using the sse plugin. I will try to get a working example setup here shortly for both cases.
