Excel import exception validating entity

I have a simple import use case to import from the following excel file

The employeeProfle field is also an entity for which I want this field is loaded on the basis of of Employee code column from database.

Here is my code:

 ImportConfiguration importConfiguration = ImportConfiguration.builder(SalaryManualEntryLine.class, InputDataFormat.XLSX)
                    .addSimplePropertyMapping("employeeCode", "Employee code")
                    .addSimplePropertyMapping("grossAmount", "Gross amount")
                    .addPropertyMapping(ReferenceMultiFieldPropertyMapping.builder("employeeProfile", ReferenceImportPolicy.IGNORE_IF_MISSING)
                            .addSimplePropertyMapping("employeeCode", "Employee code")
                            .build())
                    .withPreImportPredicate(extractionResult -> {
                        SalaryManualEntryLine salaryManualEntryLine = (SalaryManualEntryLine) extractionResult.getEntity();
                        salaryManualEntryLine.setSalaryManualEntry(getEditedEntity());
                        if (salaryManualEntryLine.getEmployeeCode() == null) {
                            return false;
                        } else {
                            salaryManualEntryLineDc.getMutableItems().add(salaryManualEntryLine);
                            return true;
                        }

                    })
                    .withTransactionStrategy(ImportTransactionStrategy.TRANSACTION_PER_ENTITY)
                    .build();

The above code works if I exclude the employeeProfile column but gives exception when validating the employee profile as below:

java.lang.IllegalArgumentException: Lookup properties are not set for property [employeeProfile]
