postMessageToUser does not Work

[kodekage]

I'm currently building a bot and i'm trying to handle a message event, such that when there is a message on a channel which includes a help string the bot sends a message to a user.

I have being trying to achieve this using bot.postMessageToUser('username', 'hello i am bot', params) and it's not working 😄

I saved that expression in a variable like:

const postToUser = bot.postMessageToUser(
    'hic',
    'hello i am dionysus',
    params
  );

I used an if statement to check if it actually works:

if(postToUser){
    console.log("Posted to the User");
  }

Unexpectedly it logs Posted to User When it actually does not on slack

Please how can i resolve this or still achieve my goal? I'd really appreciate all the help i can get

I'm using "slackbots": "^1.2.0"

I have the same problem. bot.postMessageToUser(user, message) doesn't work.

My code:

bot.on('message', data => {
  if (data.type !== 'message' || data.subtype === 'bot_message') {
    return;
  }

  handleMessage(data);
});

function handleMessage(data) {
  let user = data.user;     // I tried also user data.client_msg_id
  console.log(`user`, user);    // it shows somethings like `user UP23WKQXX`
  let message = data.text;

  if (message.includes(' help')) {
    runHelp(user);
  }
}

function runHelp(user) {
  bot.postMessageToUser(user, `message`);
}

bot.postMessageToUser(user, message) doesn't work. It gives error Assertion failed: user not found.

How to get user name?
