Hello, I have been facing some odd is issues with Pulumi and GCP Uptime Check we added recently uptime checks to our pulumi stack, we create the uptime check like this

ucc, err := monitoring.NewUptimeCheckConfig(ctx, name, &monitoring.UptimeCheckConfigArgs{
		DisplayName: pulumi.String("uptime check example"),
		HttpCheck: &monitoring.UptimeCheckConfigHttpCheckArgs{
			Path:          pulumi.String(fmt.Sprintf("/%s/status", "github")),
			Port:          <http://pulumi.Int|pulumi.Int>(443),
			RequestMethod: pulumi.String("GET"),
			UseSsl:        pulumi.Bool(true),
			ValidateSsl:   pulumi.Bool(true),
		},
		MonitoredResource: &monitoring.UptimeCheckConfigMonitoredResourceArgs{
			Labels: pulumi.StringMap{
				"host": pulumi.String(targetUrl),
			},
			Type: pulumi.String("uptime_url"),
		},
		Period:  pulumi.String("60s"),
		Timeout: pulumi.String("10s"),
	})

This was working fine, but then we decided to add an alert policy for this uptime check Note: here we forward the uptime check created previously

args := monitoring.AlertPolicyArgs{
		DisplayName: pulumi.String(name),
		Combiner:    pulumi.String("AND"),
		Conditions: monitoring.AlertPolicyConditionArray{
			monitoring.AlertPolicyConditionArgs{
				DisplayName: pulumi.String("Health check alerts for github %s", service.ShortName),
				ConditionThreshold: monitoring.AlertPolicyConditionConditionThresholdArgs{
					Filter:   pulumi.Sprintf("metric.type=\"<http://monitoring.googleapis.com/uptime_check/check_passed\|monitoring.googleapis.com/uptime_check/check_passed\>" AND metric.label.check_id=\"%s\" AND resource.type=\"uptime_url\"", uptimeCheck.UptimeCheckId),
					Duration: pulumi.String("60s"),
					Trigger: monitoring.AlertPolicyConditionConditionThresholdTriggerArgs{
						Count: pulumi.IntPtr(1),
					},
					ThresholdValue: pulumi.Float64Ptr(1),
					Comparison:     pulumi.String("COMPARISON_LT"),
					Aggregations: monitoring.AlertPolicyConditionConditionThresholdAggregationArray{
						monitoring.AlertPolicyConditionConditionThresholdAggregationArgs{
							AlignmentPeriod:  pulumi.String("60s"),
							PerSeriesAligner: pulumi.String("ALIGN_COUNT_TRUE"),
						},
					},
				},
			},
		}
		NotificationChannels: "alerts",

This worked fine in the first deployment, but the subsequent ones started to fail.

error: deleting urn:pulumi:env::company::gcp:monitoring/uptimeCheckConfig:UptimeCheckConfig::uptime-check-github: 1 error occurred:
Error when reading or editing UptimeCheckConfig: googleapi: Error 400: Request contains an invalid argument.

What a noticed is the new uptime checks got created in our account, but GCP entered in some weird state where it could not delete the previous uptime check, the only way I managed to fix the stack was by deleting the old uptime checks manually, I also noticed that the old uptime checks still had alert policies attached to them Is there any idea of what could be happening? I personally can’t find what I have missed and there’s not much documenation around pulumi and uptime checks.
