Sir, these are my telegram channel details, my device is transferring the data that’s why I didn’t put its details.
I’m not getting what changes to update.

Your telegram_bot_id should be “bot” followed by the api key that you got when you created a new bot ( check this in the BotFather chat )

unnamed

Your configuration file has some values missing like the key of the bot you receive and check if you have entered the IDs correctly, hope it helps.

Thanks buddy, its working now. I didn’t put the API key of the bot.
