My usage is pretty basic:

import fetch from 'node-fetch';
const res = await fetch(url, GenerateRequestOptions(token));

and the fetch call yields a warning:

[DEP0066] DeprecationWarning: OutgoingMessage.prototype._headers is deprecated

As I'm not accessing headers directly, so I guess the fix should be in the package?

I got this too, but only on the occasional request, not all. Did you ever get to the bottom of it? I'm also using express 4.17.1, so I'll be looking there next. – Ben Steward Nov 09 '19 at 15:51
Nope, I think it just disappeared after package upgrade. – SagiLow Nov 09 '19 at 16:00
Interesting, I’m on the latest express and latest node-fetch. There must be something else in my app sending stuff LOL. – Ben Steward Nov 09 '19 at 17:10
@BenSteward did you get rid of the [DEP0066] ? Having same issue and also have latest version installed "node-fetch": "^2.6.0" – Ricardo stands with Ukraine Mar 04 '20 at 15:17

Node documentation https://nodejs.org/api/cli.html#cli_node_options_options explains can have a Environment Variable NODE_OPTIONS='--trace-deprecation' but when added to my AWS Lambda no extra information was displayed :( – Ricardo stands with Ukraine Mar 04 '20 at 17:42
So sorry @Riga I think I resolved this for myself, but don't remember how, or if I even resolved it "on purpose" to be honest. – Ben Steward Mar 04 '20 at 17:58
