Apache ReverseProxy not working with Node and SSL - node.js

Question

I'm trying to setup my app on HTTPS on a web server. I have a valid certificate that is installed on my InMotion host using AutoSSL. I have the node app running on my Centos server on port 3000 and my apache SSL server running on port 443. To route requests made to my website, I am attempting to create a reverse-proxy. I made a file called default-site.conf which is stored in /etc/http.d/conf.d and has the following contents:
<VirtualHost _default_:443>
SSLProxyEngine on
ServerName example.com
ServerAlias www.example.com
ProxyRequests Off
ProxyPreserveHost On
ProxyVia Full
<Proxy *>
Require all granted
</Proxy>
ServerAdmin info#example.com
DocumentRoot /home/USER/my-app/public
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
SSLCertificateFile /home/USER/ssl/certs/certificate.crt
SSLCertificateKeyFile /home/USER/ssl/keys/certificate.key
ProxyPass / https://example.com:3000/
ProxyPassReverse / https://example.com:3000 /
<Directory "/home/USER/my-app/public">
AllowOverride All
</Directory>
</VirtualHost>
I will emphasize that the app is accessible at http://example.com:3000 (insecure) but when I attempt to go to https://example.com (secure) I get my blank index.html with a 404 error:
[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (index.js, line 0)

Answer 1

I managed to fix this issue by completely simplifying my config to the following two lines:
ProxyPass / http://127.0.0.1:3000/
ProxyPassReverse / http://127.0.0.1:3000/
This may not be the most flexible approach but it reroutes the traffic the way I need it to be routed, so for my purposes, it works.
