Unable to Ignore Differences of a single Object in an Array

[joshwright10]

I am trying to create a process which will allow external tooling to create a Sync Window for an AppProject so that engineers and developers can simply add a "1h" Window to Pause the sync for their application while they troubleshoot an issue on the live cluster.

The process works well, but the declarative nature of GitOps wipes out my out of band Sync Window created by the REST API before it has a chance to be useful.

I have tried adding an ignoreDifferences option to Argo at the System level and App level, but I can't get it to just ignore specific objects in the .spec.syncWindows[] array.

For example, I have tried the following:

ignoreDifferences:
  - kind: AppProject
    jqPathExpressions:
      - .spec.syncWindows[]? | select(.description | startswith("Created by Automation"))

This is what the JSON looks like from a GET request to the REST API.

{
    "spec": {
        "syncWindows": [
            {
                "description": "Created in GitOps",
                "kind": "deny",
                "schedule": "10 1 * * *",
                "duration": "1m",
                "applications": [
                    "*-prod"
                ],
                "manualSync": true
            },
            {
                "description": "Created by Automation",
                "kind": "deny",
                "schedule": "10 1 * * *",
                "duration": "1m",
                "applications": [
                    "website01"
                ],
                "manualSync": true
            }
        ]
        
    }
}

I would expect that the ignoreDifferences would simply ignore the object in the array where the description is "Created by Automation" and sync as normal.

However, Argo CD is instead syncing the AppProject and removing the Sync Window that I created using the REST API.

Is it possible to Ignore just a single object in an array based on a value in that array object?

I expected that this item in the array would
