Action does not error when message could not be sent

[gr2m]

Description

I'm new to Slack's APIs, and I only installed the action. I missed to install the new app to the channel I want it to send a message to, the PR at #5 would have saved me some time ;)

I wanted to let you know that although the error is logged to the output, the action still exists as if sending the message succeeded.
