Error when receiving warning for posting repeated URLs

[nlw0]

I am making a bot that posts news articles links. This error message appears when a repeated url is posted, and Slack answers with a warning that the url was already posted recently so it will not be unfurled. It appears the client is having some trouble reading this answer...

Another error today, I suppose it relates to reading JSON responses?...

There are a few newly added message types that I haven't gotten around to supporting.

It looks there is an issue with:

• member_joined_channel
• bot_message

I'm aware of the bot_message issue and will be adding support for that type shortly. Thanks for reporting!
