Attachment must be ether alert_link or message

[D2SI]

Hello,

Thanks a lot for the App!

I have some alerts configured the way I need them but I got this splunkd WARN:

01-09-2020 07:21:33.275 +0000 WARN sendmodalert - action=slack STDERR - Validation warning: Parameter attachment must be ether "alert_link" or "message"

while the configuration is 'Attachment = none', and it says the setting is optional. The alert output is fine.

I guess the WARN could just be ignored but I wanted to post here so it can be 'fixed' maybe in the next version.

Thanks
