Problem

Agent variables are not available when using a Webhook template in Bamboo to send Notifications about Agent changed state (Agent online/Agent offline).

Environment

• Bamboo Data Center
• Webhook templates
• Notifications (agent related)

Steps to Reproduce

1. Create a new Webhook template, call it "AgentStateWebhook"
2. Add a payload such as:
   The variables below are hypothetical as they don't exist, but were inspired by the FTL code that sends email notifications

   {
     "agent.id": "${bamboo.agent.id}",
     "agent.name": "${bamboo.agent.name}",
     "agent.state": "${bamboo.agent.state}"
   }
   

3. Add a System Notification for type "Agent online/offline" and select the Webhooks as the Recipient type. Choose the Webhook name "AgentStateWebhook"
4. Stop/Start an Agent

Expected Results

• As Webhooks are available as a Recipient to Agent change state events, Bamboo should provide and parse the Agent-related variables and send the Webhook

Actual Results

• Bamboo fails with:

Workaround

• In Bamboo, instead of using a Webhook recipient in the Notification rule, use an alternative Recipient type based on email
