http.request TypeError: "listener" argument must be a function

Error: TypeError: "listener" argument must be a function

Code to reproduce:

let url: string = `http://localhost:${servicePort}/v1/upload?fileName=${OUTPUT_FILE}`
let req = http.request(url, options)
let readStream = fs.createReadStream(ORIGINAL_FILE)
readStream.pipe(req)
readStream.on('error', err => console.log(`READSTREAM: Failed to pipe: ${JSON.stringify(err)}`))
readStream.on('end', () => {
   console.log(`READSTREAM: Completed read.`)
   return;
})

The stack points to let req = http.request(url, options) as the problem line

After switching to use the request library, I have no issue. Seems to be an underlying issue with the http module.

Can you share the stack, as well as the value of options?

Code snippet with options:

let req = http.request(url, {
   headers: {
      'Transfer-Encoding': 'chunked'
   },
    method: 'POST'
}, () => console.log('Made it to callback'))

Are you sure you're running version 12.13.1? If so, how did you install it? Is it an official build installed from nodejs.org, nvm, etc.? The reason I ask is because the first stack frame you've provided is:

at new ClientRequest (_http_client.js:164:10)

But, looking at at the code for v12.13.1, that line appears to be:

node/lib/_http_client.js

Line 164 in 525fd9c

}

This is correct, this issue can be closed. Nodemon was calling Node 8, but my current version was v12.13.1. Thanks for your quick reply!
