[RESULT_ERRORS] parsed but empty

Describe the bug

First of all, thanks for this project

I am trying to configure a custom alert provider but fail to pass the result of the else check.

My custom conf is the following one :

custom:
        url:  http://*************/gatus/notify
        method : "POST"
        headers: {"X-Auth-Token": "****************"}
        body: |
          { "endpoint": "[ENDPOINT_NAME]",
            "conditions": "- [RESULT_ERRORS] -",
            "description": "[ALERT_DESCRIPTION]",
            "endpoint_url": "[ENDPOINT_URL]",
            "resolved": "[ALERT_TRIGGERED_OR_RESOLVED]"
          }
        default-alert:
          failure-threshold: 2
          success-threshold: 1
          send-on-resolved: true

What do you see?

From my webhook end, here my what I receive :

{
    "endpoint": "Calcul mental", 
    "conditions": "-  -", 
    "description": "calcul.stchepinsky.net is down", 
    "endpoint_url": "[REDACTED]",  
    "resolved": "TRIGGERED"
}

What do you expect to see?

I expect to receive the healthcheck result which works well for my endpoint as I recieve this health check on ntfy in parrallel :

🔴 [STATUS] (502) == 200
🟢 [CERTIFICATE_EXPIRATION] > 7d

List the steps that must be taken to reproduce this issue

1. Start the application
2. Configure a custom alert provider using the [RESULT_ERRORS] provider
3. Configure the following endpoint :

      - name: Test
        group: "Public services"
        interval: 10s
        url: https://example.com
        conditions:
          - "[STATUS] == 200"
          - "[CERTIFICATE_EXPIRATION] > 7d"
        alerts:
          - type: custom
            description: "test is down"
          - type: ntfy
            description: "test is down"

4. Generate an downtime or resolve it

Version

v5.15.0

Additional information

I'll try to downgrade to previous version to try if it'll resolve the issue or not. I'll post the result once down below.
