Filling out the following details about bugs will help us solve your issue sooner.

Reproducible in:

package version: @slack/bolt => 2.0.1

node version: v12.16.1

OS version(s): Mac OS

Steps to reproduce:

Code as same mentioned in the website.

// Listens to incoming messages that contain "hello"
app.message('hello', async ({ message, say }) => {
  // say() sends a message to the channel where the event was triggered
  await say({
    blocks: [
      {
        "type": "section",
        "text": {
          "type": "mrkdwn",
          "text": `Hey there <@${message.user}>!`
        },
        "accessory": {
          "type": "button",
          "text": {
            "type": "plain_text",
            "text": "Click Me Button"
          },
          "action_id": "button_click"
        }
      }
    ]
  });
});

__Button Listener__

app.action({ action_id: 'button_click' },
  async ({ action, ack, context }) => {
    await ack();
    try {
      const result = await app.client.reactions.add({
        token: context.botToken,
        name: 'white_check_mark',
        timestamp: action.ts,
        channel: action.channel.id
      });
    }
    catch (error) {
      console.error(error);
    }
  });

Expected result:

The action listener has to be invoked.

Actual result:

No events fired in the Bolt app.

What actually happened
I see the following in ngrok POST /slack/actions 404 Not Found

Attachments:

Logs, screenshots, screencast, sample project, funny gif, etc.

👋 Bolt framework receives all kinds of events with the path /slack/events and properly dispatch them for you. Set the /slack/events also for the Request URL in the Interactivity section.

Thank you so much for the quick reply. IT WORKED 🤩.

It would have been good if the document has some reference mentioning, about the URLs to use for events and interactivity. Spent close to 4 hours yesterday. Thanks again @seratch !!!!
