Inactive Employees Get Error in Approval Rule. What kind of rule should be written?

After people are terminated, when we add documents for these people, the system gives us an error.

How can we solve this problem?

I found the code below and added it to the approval route, but it did not work. What can you suggest?

' ((getNewDoRByTransactionIdResponse.result.AuthorizationRequired == "Y") AND (NOT (GetAllRepresentatives("HR_REP",Task.payload.getRepresentativeListWrapperResponse.result) contains transactionApprovalRequest.Requestor)) '

(We use approval rules)

The problem is that this approval route is included in the wrong rule.

The system gives an error when document records are entered for inactive employees.

When a document record is entered for active employees, it must be included in the correct approval rule in the system.
