Unable to finish TLS handshake for my express webserver - node.js

Question

Here's my webserver, most parts not included in favor of being concise.
server.js
const https = require('https');
const app = require('express')();
const port = 1000;
const options = {
key : getKey(),
cert: getCert(),
ciphers: getCiphers(),
passphrase: "abcd",
rejectUnauthorized: true,
requestCert: true
};
const server = https.createServer(options, app);
server.on('clientError', function (err) {
console.log('received client error');
console.log({err});
})
server.on('connection', function (err) {
console.log('client connected');
})
server.listen(port);
To test my server, I run a connection commands with openssl
openssl s_client -connect localhost:1000 \
-servername localhost \
-CAfile etc/root-cert/ca.cert.pem \
-cert etc/certs/client.cert.pem \
-key etc/private/client.key.pem
This returns the following output, which indicates that the TLS connection was successful (as far as I'm aware):
CONNECTED(00000005)
depth=2 C = US, ST = California, O = Hackysack, CN = Hackysack Root CA
verify return:1
depth=1 C = US, ST = California, O = Hackysack, CN = Hackysack Intermediate CA
verify return:1
depth=0 C = US, ST = California, O = Hackysack, CN = localhost
verify return:1

However, in my server terminal logs I see that I receive a clientError when trying to make this call via HTTPS request.
{
err: Error: socket hang up
at connResetException (internal/errors.js:639:14)
at TLSSocket.onSocketClose (_tls_wrap.js:1063:23)
at TLSSocket.emit (events.js:412:35)

at Socket.emit (events.js:400:28)
at TCP.<anonymous> (net.js:686:12) {
code: 'ECONNRESET'
}
}
Here's my client request:
const https = require('https');
const options = {
hostname: 'localhost',
port: 1000,
method: "POST",
path: "/test",
cert: getClientCert(),
key: getClientKey(),
passphrase: "abcd",
ciphers: getCiphers()
ca: getCA(),
}
const request = https.request(options);
I noticed this error only started happening when I included requestCert: true when I created the server. I think something must be going wrong with my client side for this to be the case. The main problem with debugging this is that I'm not receiving a good error when it fails the handshake.
How can I better debug this issue?
