I need to get the child parameter value from Graphql.

Here is my Graphql query:

 {
  foods(type: "fries") {
    drinks {
      calorie(joule :1500) {
        name
      }
    }
  }
}

I can get the type field easily but also I need to get the joule value. When I investigate this problem I find a file called generated.go, so I found the following code part for sending parameters to the target function;

resTmp, err := ec.ResolverMiddleware(ctx, func(rctx context.Context) (interface{}, error) {
    ctx = rctx // use context from middleware stack in children
    return storage.FoodFinder(rctx, args["type"].(string)) //only args sended to function.
})

I can get whole raw data from rctx variable but I don't wanna parse that, seems grueling.

So How can I get joule, one of that child fields from rctx context variable?

so, on my case (i created audit logging for graphql queries) you can try to get root field context

rfc := graphql.GetRootFieldContext(ctx)
if rfc == nil {
    return next(ctx)
}

then you can catch children arguments:

for _, value := range rc.Field.Arguments {
    if value.Value.Children != nil {
        for _, v := range value.Value.Children {
