Some values are not being replaced when using custom alerting

[aalmenar]

Describe the bug

i have the following configuration:

  custom:
    url: "https://myalertserver/postendpoint"
    method: "POST"
    body: |
      {
        "message": "[ALERT_TRIGGERED_OR_RESOLVED]: [ENDPOINT_GROUP] - [ENDPOINT_NAME] - [ALERT_DESCRIPTION] - [RESULT_ERRORS]"
      }

What do you see?

Im receiving the messages like this:

TRIGGERED: Group_Name - Endpoint_Name - -

or

RESOLVED: Group_Name - Endpoint_Name - -

what makes me think, ALERT_DESCRIPTION and RESULT_ERRORS are coming empty.

What do you expect to see?

TRIGGERED: Group_Name - Endpoint_Name - A description - [CONNECTED] (false) == true
