spring data rest put 400 bad request - angularjs

Question

with entity:
#Entity
#Table(name="question",schema="fire")
public class Question {
private Integer questionId;
private String questionStatement;
private Ui ui;
private OptType optType;
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
#Column(name="question_id",unique=true,nullable=false)
public Integer getQuestionId() {
return questionId;
}
public void setQuestionId(Integer questionId) {
this.questionId = questionId;
}
#Column(name="question_statement")
public String getQuestionStatement() {
return questionStatement;
}
public void setQuestionStatement(String questionStatement) {
this.questionStatement = questionStatement;
}
#ManyToOne(fetch=FetchType.EAGER,cascade=CascadeType.MERGE)
#JoinColumn(name="ui_id")
public Ui getUi() {
return ui;
}
public void setUi(Ui ui) {
this.ui = ui;
}
#ManyToOne(fetch=FetchType.EAGER,cascade=CascadeType.MERGE)
#JoinColumn(name="opt_type_id")
public OptType getOptType() {
return optType;
}
public void setOptType(OptType optType) {
this.optType = optType;
}
}
and its repository defined to use with spring data rest, I am able to fetch list of all questions. In angularjs application I define list of questions as
$scope.questions = response._embedded.questions;
Now If do following I get bad request in chrome console and jackson exception on server
var headerz = [];
headerz['Content-Type'] = 'application/json';
headerz[$scope.csrfHeaderName] = $scope.csrfToken;
$http.patch(url,question,{
transformRequest : angular.identity,
headers : headerz
})
Following is error in eclipse:
