Send a message to discord channels via google apps script

Question

I am using some scripts to send message to discord via google apps script... I used a function such as :

function postMessageToDiscord(){

  message = "Hello World!";

  var discordUrl = "https://discordapp.com/api/webhooks/XXXXX";
  var payload = JSON.stringify({content: message});

  var params = {
    headers: {
      'Content-Type': 'application/x-www-form-urlencoded'
    },
    method: "POST",
    payload: payload,
    muteHttpExceptions: true
  };

  var response = UrlFetchApp.fetch(discordUrl, params);
  Logger.log(response.getContentText());
}

Everything was working perfectly for weeks, but since 2 or 3 weeks, nothing is sent to discord anymore... Could someone help me to understand what's going on?

Thanks a lot :)

Answer 1

How about the following modifications?

Pattern 1:

From:

var params = {
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded'
  },
  method: "POST",
  payload: payload,
  muteHttpExceptions: true
};

To:

var params = {
  method: "POST",
  payload: payload,
  muteHttpExceptions: true,
  contentType: "application/json"
};

Pattern 2:

From:

var payload = JSON.stringify({content: message});

To:

var payload = {content: message};

Note:

• In my environment, I could confirm that both patterns works fine while the error of {"message": "Cannot send an empty message", "code": 50006} occurs when your script is run.
• If your webhook cannot be used, how about setting it again? Ref

If this was not the direct solution of your issue, I apologize.
