Undefined IP on requests

I'm using express and mongo on Deno, and i'm also trying to use express-rate-limit, however, i'm getting the following error on rate-limit because the request.ip is undefined:

ValidationError: An undefined 'request.ip' was detected. This might indicate a misconfiguration or the connection being destroyed prematurely. See https://express-rate-limit.github.io/ERR_ERL_UNDEFINED_IP_ADDRESS/ for more information.

I've found this answer on a similar question that suggests adding app.set('trust proxy', 1); i tried it, but the ip continues undefined.
