How to use autocannon for testing self signed certificates

[hrishikeshgjoshi]

I am using autocannon to test WebServer performance and it trows error after test is executed before it provides request status as follows.
http-parser.js:126
throw err;

Error: Cannot use a destroyed histogram

Please post the test config.

Here is the test script for the same.

"use strict";

const autocannon = require("autocannon");

const loadSpec = {

How is this related to testing a server with self signed certificate? Do you mean that you don't see this error when the same test is run against a different http server?

Also, it'd be great help in debugging if you could post a reproducible repo as an example.

[hrishikeshgjoshi]

Yes if I run this test code to use http url. I do not see this error. Do you see any obvious mistake in code posted above. I will try to provide some reproducible repo soon.

@hrishikeshgjoshi i think you can run your tests like this
NODE_TLS_REJECT_UNAUTHORIZED=0 node runTest.js
