[BUG] 99designs/gqlgen/tracer.go: panic cause nil pointer
I was implement graphQL subscription, it just a simple subscription like this (https://gqlgen.com/recipes/subscriptions/) but I want to stop the subscription in server side so I close the response channel when there is no more data. But I found that in 99designs/gqlgen/tracer.go#L119 , there is missing check response nil. I think because we have to trace even if the response is nil, but when we get Data and Error from response it lead to panic.
Version of dd-trace-go
v1.65.1
Describe what happened:
