Azure Bot Framework Emulator + Ngrok – Error : Failed to spawn ngrok

I can’t seem to make Azure Bot Framework Emulator work with Ngork.

Environment :

• Ubuntu 22.04
• Python3

Steps I followed :

• Create a bot with the Bot Framework SDK
  • => bot works fine locally with the Emulator
• Tutorial: Provision a bot in Azure
• Tutorial: Publish a basic bot
  • => bot works fine in Azure with the Test Web Chat
• install and configure Tunneling (ngrok)
  • => the status page of Ngrok (http://localhost:4040/status) says it is Onine
    
  • => "Ngrok Status Viewer" says "Tunnel Status" is on error in the Emulator
    
  • => I have error messages in the Emulator : Failed to spawn ngrok. Please go to the Ngrok Status Viewer and download the log file for a more detailed view of the error.

{
  "error_code": 102,
  "status_code": 400,
  "msg": "invalid tunnel configuration",
  "details":
    {
      "err": "yaml: unmarshal errors:n line 1: field region not found in type config.HTTPv2Tunneln line 1: field path not found in type config.HTTPv2Tunnel",
    },
}

Edit 1 : following @sairamtadepalli-mt ‘s suggestion

If I change Ngrok’s port (web_addr) in the config, I get a new error :

Connecting to bot on https://XXX.azurewebsites.net/api/messages
ngrok reconnected.
ngrok listening on http://localhost:36599
ngrok traffic inspector:
Will bypass ngrok for local addresses
Failed to spawn ngrok. Please go to the Ngrok Status Viewer and download the log file for a more detailed view of the error.
Error: The bot is remote, but the service URL is localhost. Without tunneling software you will not receive replies.
Connecting to bots hosted remotely
Configure ngrok

Here is what I see in the Status Viewer and console (still the same error as initially…) :

Error in the Emulator "Ngrok Status Viewer" :
Looks like the ngrok tunnel does not exist anymore. Try reconnecting to Ngrok or examine the logs for a detailed explanation of the error.

Error in the console :

Failed to spawn ngrok Error: {"error_code":102,"status_code":400,"msg":"invalid tunnel configuration","details":{"err":"yaml: unmarshal errors:n  line 1: field region not found in type config.HTTPv2Tunneln  line 1: field path not found in type config.HTTPv2Tunnel"}}
