I am trying to map the object but in meantime it gives me the following error: TypeError: values.map is not a function. I am new to React development.

I am using this method in Redux method

Code

export function createEvent(values) {

  let modifyValue = values.map(newValue => {

    return {

      subject: newValue.id,

      taskType: newValue.tasktype,

      time: newValue.time,

      date: newValue.date,

      notes: newValue.notes,

      createdAt: newValue.createdAt,

      updatedAt: newValue.updatedAt,

      deletedAt: newValue.deletedAt,

      userId: newValue.userId,

      customerId: localStorage.getItem(customerValue),

      start: newValue.start,

      end: newValue.end

    };

  });

  return dispatch => {

    axios

      .post(api/diary/create, modifyValue)



      .then(response => {

        return dispatch({ type: SET_DIARY_TASK_SUCCESS, data: response });

      })



      .catch((xhr, status, err) => {

        return dispatch({ type: SET_DIARY_TASK_FAILURE, data: xhr });

      });

  };

}
