how to get parent member in groovy fccs

Summary:

We are trying to run groovy rules to run consolidation on the OTPS entity variable and also would like to run consolidation on the parent entity member however getting issues with member function on groovy api.

import groovy.json.JsonOutput
import oracle.epm.api.model.Dimension
import oracle.epm.api.model.Cube
import com.hyperion.essbase.client.data.Member

// Access the application and cube
def app = operation.application
def cube = operation.cube

// Retrieve the dimension and member
def dimension = app.getDimension("Entity")
def member = dimension.getMember(sEntity)

// Get the parent member
def parentMember = member.getParent()

// Execute Consolidate rule for parent
