How to apply labels to ad groups (Google Ads API v1)?

[vgapites...@gmail.com]

I'm working on a function that takes an existing label and applies it to selected ad groups (using their ad group ids). Not sure if I'm setting this up right since I keep getting exceptions, ex: 

	Name	Value	Type
▶	Failure	{{ "errors": [ { "errorCode": { "newResourceCreationError": "CANNOT_SET_ID_FOR_CREATE" }, "message": "Do not set the id field while creating new resources.", "trigger": { "int64Value": "1052616624" }, "location": { "fieldPathElements": [ { "fieldName": "operations", "index": "0" }, { "fieldName": "create" }, { "fieldName": "resource_name" } ] } } ] }}	Google.Ads.GoogleAds.V1.Errors.GoogleAdsFailure

This is the resource name: "customers/9878485465/adGroupLabels/54654643~459484545"

Can someone take a look at this and tell me what I'm doing wrong

                AdGroupLabel adGroupLabel = new AdGroupLabel();
                adGroupLabel.ResourceName = ResourceNames.AdGroupLabel(long.Parse(client.Config.LoginCustomerId), id, long.Parse("459484545"));


                // Create the operation.
                AdGroupLabelOperation operation = new AdGroupLabelOperation()
                {
                    Create = adGroupLabel
                };
                //AdGroup adGroup = new AdGroup();
                //adGroup.ResourceName = ResourceNames.AdGroup(client.Config.LoginCustomerId.ToString(),
                //    id);


                //AdGroupOperation operation = new AdGroupOperation()
                //{
                //    Update = adGroup,
                //    UpdateMask = FieldMasks.AllSetFieldsOf(adGroup)
                //};


                try
                {
                    // Update the ad group.label
                    MutateAdGroupLabelsResponse retVal = adGroupLabelService.MutateAdGroupLabels(
                        client.Config.LoginCustomerId.ToString(), new AdGroupLabelOperation[] { operation });


                    // Display the results.
                    MutateAdGroupLabelResult adGroupLabelResult = retVal.Results[0];


                    Console.WriteLine($"Ad group with resource name '{adGroupLabelResult.ResourceName}' " +
                        "was updated.");
                }
                catch (GoogleAdsException e)
                {
                    Console.WriteLine("Failure:");
                    Console.WriteLine($"Message: {e.Message}");
                    Console.WriteLine($"Failure: {e.Failure}");
                    Console.WriteLine($"Request ID: {e.RequestId}");
                }
            }
