match_values is a required field but when setting anything and applying the plan, you get an error

Actual Behaviour

match_values is a required field but when setting anything and applying the plan, you get an error when Operator is Any

@httran13, Thank you for opening this issue. I have opened the linked PR to address this issue. match_values are now optional if the operator is set to Any. If the operator is anything other than Any you will receive the below error:
