Accept: application/json; charset=UTF-8
Content-Type: application/json

{
  "foo" : null
}

Example response

400: Bad Request
Content-Type: application/json; charset=UTF-8

{
  "message": "Could not set property \"foo\", unsupported type: null",
  "exception": "PropertyValueException",
  "fullname": "org.neo4j.server.rest.web.PropertyValueException",
  "stacktrace": [
    "org.neo4j.server.rest.domain.PropertySettingStrategy.setProperty(PropertySettingStrategy.java:141)",
    "org.neo4j.server.rest.domain.PropertySettingStrategy.setProperties(PropertySettingStrategy.java:88)",
    "org.neo4j.server.rest.web.DatabaseActions.createNode(DatabaseActions.java:214)",
    "org.neo4j.server.rest.web.RestfulGraphDatabase.createNode(RestfulGraphDatabase.java:238)",
    "java.lang.reflect.Method.invoke(Method.java:606)",

Content-Type: application/json

{
  "foo" : {
    "bar" : "baz"
  }
}

Example response

400: Bad Request
Content-Type: application/json; charset=UTF-8

{
  "message": "Could not set property \"foo\", unsupported type: {bar\u003dbaz}",
  "exception": "PropertyValueException",
  "fullname": "org.neo4j.server.rest.web.PropertyValueException",
  "stacktrace": [
    "org.neo4j.server.rest.domain.PropertySettingStrategy.setProperty(PropertySettingStrategy.java:141)",
    "org.neo4j.server.rest.domain.PropertySettingStrategy.setProperties(PropertySettingStrategy.java:88)",
    "org.neo4j.server.rest.web.DatabaseActions.createNode(DatabaseActions.java:214)",
    "org.neo4j.server.rest.web.RestfulGraphDatabase.createNode(RestfulGraphDatabase.java:238)",
    "java.lang.reflect.Method.invoke(Method.java:606)",
    "org.neo4j.server.rest.transactional.TransactionalRequestDispatcher.dispatch(TransactionalRequestDispatcher.java:139)",
    "org.neo4j.server.rest.security.SecurityFilter.doFilter(SecurityFilter.java:112)",
