Aria Automation Deployment Update fails with Unable to find flavor error

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

VMware Aria Automation deployment updates via cloud template fail. The following error message is observed during the update process:

"Failed to process ebs event: SubscriberID: quota-service and SubscriptionID: resource-quota-policy-service-deployment-approval failed with the following error: Error occurred - : Unable to find flavor"

Environment

VMware Aria Automation 8.18.1

Cause

For initial deployments without flavor mapping, a placeholder flavor without a name is created, and the flavor mapping is not saved. When updating the existing deployment, the system attempts to fetch the placeholder flavor where the name is empty. Because the system only performed a Null check and lacked an empty string check, the flavor fetch operation fails.

Resolution

Resolution : This is a known issue which will be fixed in an upcoming patch 6 release of Aria Automation 8.18.1.

Workaround : 
For deployments already impacted by this error where orphaned resources (such as duplicate-named disks like disk0) exist:

1. Identify orphaned volumes in vCenter that are attached to the VM but not tracked in the Aria Automation deployment resource record.
2. Manually detach and delete the orphaned volumes in vCenter.
3. Alternatively, correct the deployment by importing or registering the resources with unique names.
