slack api failing to send messages due to channel_not_found

[InventoRyAlpaca]

Slack API error: The request to the Slack API failed. (url: https://www.slack.com/api/chat.postMessage) The server responded with: {'ok': False, 'error': 'channel_not_found'}

solution was to invite the bot to the channel, as mentioned here: https://www.ibm.com/docs/en/z-chatops/1.1.0?topic=slack-adding-your-bot-user-your-channel

simply just @botName in the channel you want to use and slack will ask if you want to invite the bot
