Uncaught exception: AssertionError [ERR_ASSERTION]

[SergeyFromHell]

In function onConnect you use assert.equal(head.length,0).
If assertion fails, it leads to uncaught process exception.
Please process this as an error so than exception is not beign thrown to nowhere.

This problem arises when I use request module and working with bad proxies.

Having same issue while using proxy and "non existing domain" url

const options = {
    uri: url,
    timeout: requestTimeout,
    resolveWithFullResponse: true,
    proxy: `http://${process.env.PROXY_USERNAME}:${process.env.PROXY_PASSWORD}@us.smartproxy.com:10000`
  }

Bumped into exactly the same error in a batch process which killed the whole thing.

Any way to work around this issue?

[jjason685]

process.on('uncaughtException', err => { if (err.name === 'AssertionError') { console.log('Assertion error', err); } });

Only way to avoid this even though it isn't exactly good practice. Alternatively, you could rebuild the tunnel-agent library, but this is a fast solution if you're being lazy.
