📝 Overview

When using the Slack app, you might encounter the following request results:

{ "ok": false, "error": "channel_not_found" }

{"ok": false,"error": "not_in_channel"}

This guide explains how to resolve these issues.

✋ Cause 1: Incorrect Channel ID

The channel_not_found error often occurs when the channel ID is incorrect.

Follow these steps to verify the ID.

1. Open the relevant channel in the web version of Slack.

2. Check the URL format:

「https://app.slack.com/(workspace name)/(channel ID)」

3. Copy the channel ID from the URL.

1. Open the relevant channel in the Slack desktop app.

2. Right-click the channel name and select “Copy Link.”

3. The copied URL will look like this:

「https://(workspace name).slack.com/archives/(channel ID)」

4. Extract the channel ID from the URL.

The "not_in_channel" error usually means the Yoom app hasn’t been added to the channel.

1. Open the target channel in Slack.

2. Click the channel name at the top.

3. Navigate to the "Integrations" tab.

4. Under "Add app”, search for Yoom and click "Add."
