var rootCas = require('ssl-root-cas').create();
require('https').globalAgent.options.ca = rootCas;

const https = require('https');
const agent = new https.Agent({ rejectUnauthorized: false });

let url = 'https://ih1.redbubble.net/image.99400032.8054/flat';
axios.get(url, {
    responseType: 'arraybuffer',
    httpsAgent: agent
})
    .then(result => ({ buffer: result.data }))
    .catch(err => {
        debug({ err });
    });

produces this;

@Faburu do you have https_proxy env variable set when executing this?

I have exactly the same error, but mine is about https_proxy. Here is the issue: #1885

Closed in favor of #1885.
