Getting 502 Bad Gateway error with ngrok when I use https localhost url in a Node App

I'm developing a Node App. I need https for receiving callback URLs from 3rd party Apps. So I added SSL certificate.

ngrok works only with http URL (http://localhost:3000).

I'm using the command ngrok http 3000. But when I access ngrok https URL, I'm getting 502 Bad Gateway error in browser.

How do I make ngrok work with https://localhost:3000 URL.
