      I've deployed the employeerostering playground app to KIE server, created a solver and posted following body:

      {
  "employeerostering.employeerostering.EmployeeRoster": {
    "employeeList": [
      {
        "name": "John",
        "skills": {
          "employeerostering.employeerostering.Skill": {
            "name": "reading"

        }
      },
      {
        "name": "Mary",
        "skills": {
          "employeerostering.employeerostering.Skill": {
            "name": "writing"
          }
        }
      },
      {
        "name": "Petr",
        "skills": {

            "name": "speaking"
          }
        }
      }
    ],

        },
        "requiredSkill": {
          "-reference": "../../../employeeList/employeerostering.employeerostering.Employee/skills/employeerostering.employeerostering.Skill"

}

      The server throws an exception and returns 500 Internal Server Error. This is in server log:

      The important part is:

      Caused by: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `java.time.LocalDateTime` (no Creators, like default construct, exist): no String-argument constructor/factory method to deserialize from String value ('2017-01-01T00:00:00')

      I think it should be easy to fix simply by registering the JavaTimeModule as described in https://github.com/FasterXML/jackson-modules-java8.
