Remove-ObjectProperty and Add-ObjectProperty does not support indexing notation on path

[jikuja]

Describe the bug
I was deploying following content:

pipeline:

// code available by request

trigger:

{
	"name": "trigger",
	"properties": {
		"annotations": [],
		"runtimeState": "Started",
		"pipelines": [
			{
				"pipelineReference": {
					"referenceName": "pipeline",
					"type": "PipelineReference"
				},
				"parameters": {
					"filePath": "@triggerBody().folderPath",
					"fileName": "@triggerBody().fileName"
				}
			}
		],
		"type": "BlobEventsTrigger",
		"typeProperties": {
			"blobPathBeginsWith": "redacted",
			"blobPathEndsWith": "redacted.xlsx",
			"ignoreEmptyBlobs": true,
			"scope": "/subscriptions/redacted/resourceGroups/redacted-storage-dev-rg/providers/Microsoft.Storage/storageAccounts/redacted",
			"events": [
				"Microsoft.Storage.BlobCreated"
			]
		}
	}
}

parameter file:

# trigger
trigger,trigger,typeProperties.scope, "xx"
trigger,trigger,+pipelines[0].parameters.refreshDataset, "true"
trigger,trigger,-pipelines[0].parameters.fileName

Trigger parameters did not update according to my parameters.

With dry-run result are following:

$adf = publish-AdfV2FromJson -RootFolder "." -ResourceGroupName tekdata-datafactory-prod-rg -DataFactoryName tekdata-datafactory-prod-df -Location westeurope -Stage ./parameters-prod.csv -Option $opt -DryRun
($adf.Triggers | Where-Object {$_.Name -eq "trigger"}).Body.properties | ConvertTo-Json -Depth 99

results:

{                                                                                                   
  "annotations": [],
  "runtimeState": "Started",
  "pipelines": [
    {
      "pipelineReference": {
        "referenceName": "pipeline",
        "type": "PipelineReference"
      },
      "parameters": {
        "filePath": "@triggerBody().folderPath",
        "fileName": "@triggerBody().fileName"
      }
    }
  ],
  "type": "BlobEventsTrigger",
  "typeProperties": {
    "blobPathBeginsWith": "redacted",
    "blobPathEndsWith": "redacted.xlsx",
    "ignoreEmptyBlobs": true,
    "scope": "xx",
    "events": [
      "Microsoft.Storage.BlobCreated"
    ]
  },
  "pipelines[0]": {
    "parameters": {
      "refreshDataset": "true"
    }
  }
}

From result we can see that indexing notation was not resolved, instead [0] is being used as part of $root on

azure.datafactory.tools/private/ObjectProperty.ps1

Line 91 in 9b9ecc7

$obj | Add-Member -NotePropertyName $root -NotePropertyValue $value

Remove-ObjectProperty have similar issue. Update-ObjectProperty works because of the Invoke-Expressions usage.

Expected behaviour
Indexing notation on parameter file paths should work.

I could not see any mentions about this kind of limitation on documentation.

Version of PowerShell module of:

Thanks for raising it @jikuja with details.
That's correct: indexing notation is only supported for update operations.
Remove/Add with indexing path sounds like edge-scenario.
However, if you're capable of providing a solution for this, you're welcome.
