The value picker in a custom form fails to load data after applying the Aria Automation 8.18.1 Patch 1

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

• The value picker custom form is used to retrieve data from the backend Aria automation orchestrator action for multiple VMs and the subsequent attempts to use the same value picker for the next VM in the list fails. 
• The form doesn't load as the action to fetch the requested data is not triggered

Environment

• Aria Automation 8.18.1 

Cause

• Action execution is halted if at least one of the inputs is invalid (Null Value) (note: this applies only if the input is bound to another custom form field). And this is Due to the functionality introduced in 8.18.1.

Resolution

• This issue is fixed in Aria Automation 8.18.1 Patch 2. Refer KB394224

Workaround:

• Make sure to add a default value to field with id: "action". This is needed to make the field valid and the custom form to work as expected.
