OSC Calling Rest by Groovy - Error 400 Bad Request

Hi Guys,

I am trying to create a new resourcu user in OSC using REST POST Call.

While testing the script i am getting "JBO-57001: Invocation of service URL used in connection failed with status code 400 Bad Request.

My Groovy Script is:

def con = adf.webServices.criaUsuario // criaUsuario is name of the rest ws registered

def resourceRequest = [

LegalEntity: "TEST SA",

   BusinessUnit: "TEST BU",

   FirstName: "Jhon",

   LastName: "Test",

   Title: "MR.",

   ResourceEmail: "jhon.test@teste123.com",

   PersonType: "EMP",

   Username: "jhon.test",

   IndividualRoleCode: "SALES_MANAGER"

]

def httpHeaders=['Content-Type':'application/vnd.oracle.adf.resourceitem+json']

con.requestHTTPHeaders=httpHeaders

def user = con.Post(resourceRequest)

P.S: The same request described in code above works perfectly on POSTMAN
