Description

Hello, I want to log the duration of a request using a custom serializers. While doing so, I encoutered the following error :

const fastify = Fastify({
    logger: {
        serializers: {
            res(reply) {
                console.log(reply.request); // undefined
            },
        },
    },
});

When an user aborts a request, reply.request is empty.

This line should be logStreamError(reply.log, err, reply).
