Laravel验证失败并显示有效数据

Question

I am sending a valid patch request to update a users profile. I made rules to make a first name and last name required, a birthday is a date a description is spam free and gender is in a list of supplied genders. It fails immediately on the check of first name being there but I check the request and all the information is there. I hope someone can help me to see what I am doing wrong.

Axios patch request

axios.patch(
    `/api/users/${this.user.user_name}/profile/edit`, {
    firstName   : this.firstNameEdit,
    lastName    : this.lastNameEdit,
    birthday    : this.birthdayEdit,
    gender      : this.genderEdit,
    hometown    : this.hometownEdit,
    currentCity : this.currentCityEdit,
    description : this.descriptionEdit,
})

Laravel rule in request class:

public function rules()
{
  return [
     'firstName' => 'required',
     'lastName' => 'required',
     'birthday' => 'date',
     'description' => new SpamFree(),
     'gender' => Rule::in(['male', 'female', 'other'])
  ];
}

Exception:

The given data was invalid. Status 422.
