how to log cdn cloudflare ip address?

[epubreader]

req.remoteAddress does not working, how to change to req.header('x-real-ip'), mywebsite is running behind cloudflare cdn.

        serializers: {
            req: function requestSerializer(req) {
                return {
                    id: req.id,
                    method: req.method,
                    url: req.url,
                    remoteAddress: req.header('x-real-ip') || req.connection.remoteAddress,
                    remotePort: req.remotePort,
                    body: req.raw.body,
                };
            },
        },

I believe CloudFlare forwards the connecting clients IP via the CF-Connecting-IP header rather than the X-Real-IP header.
