Getting type mismatch error

[Pavan Kumar Raju]

I am getting below error when adding multiple requests to exec, but when i add multiple methods to resource method i am not seeing any issue.

val searchCreatedCostCenter = exec(

                                     CostCenterRequest.gridDataLoad("${NAME}"),

                                     CostCenterRequest.simpleSave()

                                 )

object CostCenterRequest{

  

  

  

  def suggestGridDataLoad() : HttpRequestBuilder = {

    Request.suggestGridDataLoad("Cost Center Parent Suggest Grid", Router.masterDataContext)

    

  }

  

  def simpleSave() : HttpRequestBuilder = {

    Request.simpleSave("Cost Center Simple Save", Router.masterDataContext)

.formParamMap(session=>CostCenterFormParam.simpleSave(session))

.check(jsonPath("$.tbl0[0].costCenterRowId").find(0).saveAs("COSTCENTER_ROWID"))

  }

                                     

}
