• The Webhook Outbound instance has been configured with "Basic Authentication" as "Credential Type"

Environment

Aria Operations 8.18.5

Aria Automation 8.18.1

Cause

The Webhook user authentication is failing in Aria Automation since Basic authentication is not supported anymore on Aria Automation nodes 8.18.1 as per KB "Basic Authentication" no longer supported in Aria Automation 8.18.1 

Resolution

Change the Credential type to one of the others reported on the documentation Add a Webhook Notification Plugin for Outbound Instance
