Slack allows an empty string to be passed as the text parameter to an incoming webhook, but in
Slack.prototype.send
the codeif (!message.text)
evaluates to true ifmessage.text == ''
and so no request is made. The pull request changes the conditional to check that the message text isn't null instead of casting an empty string into a boolean.
