The following extensibility error is displayed in the Aria Automation user interface:

Extensibility triggered task failed. Event ID: <Event ID>. Failure: Extensibility error received for topic compute.provision.post, eventld ='<Event ID>': SubscriberID: service-account-vro-gateway-serviceaccount, RunnableID:

Environment

VMware Aria Automation 8.18.x
VMware Aria Automation Orchestrator 8.18.x

Cause

The issue occurs because VMware Aria Automation Orchestrator is unable to establish a connection or receive a response from the vCenter Server.

Resolution

• Verify the current health and status of the target vCenter Server endpoint.
• Check if there are any active configuration changes, updates, or maintenance windows occurring on the vCenter Server.
• Engage internal vCenter Server administration team to investigate the vCenter Server logs and restore stable SDK connectivity.
• Once the vCenter Server is stable and fully operational, retry the virtual machine deployment from VMware Aria Automation.
