Telegram Send and Wait Node keeps replying with "undefined"

[everlein]

I have a send and wait telegram node that outputs

[
  {
    "data": {
      "approved": true
    }
  }
]

when the user clicks the approve button. However, no matter which button i click to always replies with undefined. Is this a normal behaviour of the webhook?

Hi i think you have to set the chat id

Or does the Send Email Node work and do you mean the response in telegram after sending Mails?

Hi I have the chat ID on my workflow. I meant after I click the approve/disapprove button and it takes me to an external url, I always get a message with ‘undefined’. It does work the way it’s intended but somehow it always responds with ‘undefined’ after I get redirected to the confirmation link.
