Failed to send to Slack: error=200

📣 Notification Service(s) Impacted
slack

🐞 Describe the bug
When setting up a slack bot following the instructions I get the following error:
Failed to send to Slack: error=200

It might just be a documentation bug.

💻 Your System Details:

• Docker

🔮 Additional context
The "workaround" for this is to simply invite the bot to the slack channel its trying to post to, but im not sure if thats intended functionality (shouldnt it be able to use general by default?)

Can you share more details on how this failed for you. I can't seem to reproduce it. You are attempting to message a slack channel through a bot that it has not been previously added to?
