Error getting while trying to load the data through worker API

Hi Everyone,

I am using below payload to load the worker through Worker API as POST Method

/hcmRestApi/resources/11.13.18.05/emps

Payload

{
"PersonNumber": "00747",
"FirstName": "John",
"LastName": "Doe",
"DateOfBirth": "1980-01-15",
"Gender": "M",
"workRelationships": [
{
"LegalEmployerName": "US1 Legal Entity",
"WorkerType": "E",
"StartDate": "2025-09-17",
"assignments": [
{
"BusinessUnitName": "US1 Business Unit",
"JobName": "Director of Payroll",
"LocationName": "Atlanta",
"GradeName": "Mgmt05"
}
]
}

}

Getting wrong workRelationships though given proper details
