Aria Automation blueprint form validation fails with "Invalid format" error

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

• Blueprint forms fail to run backend actions with an "Invalid Format" error after updating fields.
• You may see an error similar to:
  

  Invalid format. Allowed number is from <number1> to <number2> according to the selected job

Environment

Aria Automation 8.18.1

Cause

New logic introduced in Aria Automation 8.18.1 prevents vRO actions from executing if any input field is deemed "invalid" (e.g., due to empty patterns or constraint mismatches).

Resolution

• Separate constraints into distinct actions (one for min, one for max) rather than using a single regex.
• Alternatively, move custom validation logic to the External Validations tab, which executes only upon form submission.
