Node-fetch: Disable SSL verification

The other way to do is to set your own agent to the fetch call.

const fetch = require('node-fetch');
const https = require('https');

const httpsAgent = new https.Agent({
      rejectUnauthorized: false,
    });

const response = await fetch(url, {
      method: 'POST',
      headers: headers,
      body: body,
      agent: httpsAgent,
    });
