Slack Events adapter not getting triggered

Question

I am trying to build a basic slack bot but the bot is not picking up the message event. Have added the following scopes: "chat:write"

Have also subscribed for the event message.channels.

I have configured ngrok server. When I hit the endpoint from my browser I get a message saying "these are not the slack bots you are looking for" which means the server is running. But when I post a message in the channel in which the bot is added, the API is not triggered. can you please help with this?

Here is the code that I'm using:

import slack_sdk
import os
from pathlib import Path
from dotenv import load_dotenv
from flask import Flask
from slackeventsapi import SlackEventAdapter

env_path = Path('.') / '.env'
load_dotenv(dotenv_path = env_path)

app = Flask(__name__)
slack_event_adapter = SlackEventAdapter(os.environ['SIGNING_SECRET'],'/slack/events',app)

client = slack_sdk.WebClient(token = os.environ['SLACK_TOKEN'])

# client.chat_postMessage(channel = '#bi-announcements', text = "Hello World! ")

BOT_ID = client.api_call("auth.test")['user_id']

@slack_event_adapter.on('message')
def message(payload):
    print(payload)
    event = payload.get('event',{})
    channel_id = event.get('channel')
    user_id = event.get('user')
    text = event.get('text')

    if BOT_ID != user_id:
        client.chat_postMessage(channel= channel_id, text = text)

if __name__ == "__main__":
    app.run(debug=True)

Here are the slack configurations:

I'm able to send messages to slack but not able to read the messages. Any help would be greatly appreciated.

As discussed in comments, there was a rare occurrence that the created app somehow was faulty.

Creation of a new app with same configuration solved the issue.
