Slack Handler not working

Hello all,
I’m trying to use the sensu slack handler (https://github.com/sensu-plugins/sensu-plugins-slack).

It didnt work.

My config is in /etc/sensu/conf.d/handler_slack.json Here is the content:

{
“handlers”: {
“slack”: {
“type”: “pipe”,
“command”: “handler-slack.rb -j slack”
}
},
“slack”: {
“webhook_url”: “https://XXXXXX”,
“channel”: “#devops”,
“bot_name”: “rocket.cat”
}
}

When i try the handler, here is the error log that i have :

*cat sample2.json | /opt/sensu/embedded/bin/handler-slack.rb --json /etc/sensu/conf.d/handler_slack.json *
warning: event filtering in sensu-plugin is deprecated, see http://bit.ly/sensu-plugin

from /opt/sensu/embedded/lib/ruby/gems/2.3.0/gems/sensu-plugin-1.4.2/lib/sensu-handler.rb:81:in `block in class:Handler

Any idea ?

Thanks in advance

By looking at the stack trace you can see the line numbers that it is crashing on.
Look at line 26

https://github.com/sensu-plugins/sensu-plugins-slack/blob/1a7f815f0ccba27d36182fa593234fc5d8776172/bin/handler-slack.rb#L26

It is crashing when looking up the payload_template setting.

Check out the usage here:
