我在 Formik 中使用 axios post 请求,return me 400 错误

i'm using axios post request in Formik,and return me 400 error

enter image description here 请查看img,我尝试使用它,但它不起作用,我不明白为什么

<Formik        
initialValues={{email: "", password: "", firstname: "",
           lastname: "", passwordConfirm: ""}}


onSubmit={(values, {setSubmitting}) => {
        console.log(values);

        // Send a POST r`enter code here`equest
        axios.post('http://212.42.212.29:3001/auth/register', values, {
            "headers": {
                "content-type": "application/json",
            }
        }).then(function (response) {
            console.log(response);
        }).catch(function (error) {
                console.log(error.response);
            });

    }}

我的错误在Formik,我写错了值名

   <Formik 
     initialValues={{email: "", password: "", firstname: "", lastname: "", 
       passwordConfirm: ""}}
     >

**应该是**

   <Formik 
    initialValues={
          {email: "", 
           password: "", 
         **firstName: "",** 
         **lastName:""**, 
     passwordConfirm: ""}}
