Heroku | Node.js | Exception when debugging remotely - node.js

Question

I have express.js REST API server on Heroku.
I am trying to debug an error remotely. But, I receive below exception. The steps I tried to debug remote server are mentioned after this exception section.
Can someone please help me how can I debug remote node.js/express.js server?
The exception I receive:
events.js:291
throw er; // Unhandled 'error' event
^
Error: connection not allowed by ruleset

This is what I am trying:
On my local Terminal, I run heroku ps:forward 9229 --app MY_EXPRESS_APP command.
On my local Visual Code, I have the below launch.json configuration. I tried with both the configurations mentioned in it. (I understand I need only one. But I checked other Stackoverflow articles. So, I tried both the suggestions).
"configurations": [
{
"address": "TCP/IP address of process to be debugged",
"localRoot": "${workspaceFolder}",
"name": "ONE: Attach to Remote",
"port": 9229,
"remoteRoot": "/app",
"request": "attach",
"skipFiles": [
"<node_internals>/**"
],
"type": "node"
},
{
"type": "node",
"request": "attach",
"name": "TWO: Remote Heroku: Debug Remote Server",
"address": "localhost",
"port": 9229,
"protocol": "inspector",
"localRoot": "${workspaceFolder}",
"remoteRoot": "/app"
}
]
I try to run below command. When I start Debug with above one of configuration... the debugger tries to connect and pauses. And, after 2 or 3 minutes, I see the above exception on Terminal under this command.
$ heroku ps:forward 9229 --app MY_EXPRESS_APP
heroku ps:forward 9229 --app MY_EXPRESS_APP
