Change Salary approval workflow not working for custom action name

Hi All,

We are creating a new approval workflow for Manage Salary action for Managers. Currently we don't have any specific rules for different action names however, now as per requirement we have to create a new approval chain for a specific action only.

We tried below expression, but the approval chain is getting failed :-

((Worker's Salary Details.Proposed Salary Amount != Worker's Salary Details.Current Salary Amount) AND (transactionApprovalRequest.moduleIdentifier == "Change Salary") AND (Worker's Salary Details.Proposed ActionCode == "INGRADE_PAY_PROGRESSION"))

If we remove the action code condition then the approval is working fine, can you please suggest which attribute can be used to achieve this requirement.
