无法在Formik的onSubmit中调用setState函数

import { useFormik } from 'formik';

const MyForm = () => {
  const formik = useFormik({
    initialValues: {
      name: '',
      email: '',
    },
    onSubmit: (values) => {
      // 在这里调用setFieldValue函数更新字段的值
      formik.setFieldValue('name', 'new value');
    },
  });

  return (
    <form onSubmit={formik.handleSubmit}>
      <input
        type="text"
        name="name"
        value={formik.values.name}
        onChange={formik.handleChange}
      />
      <input
        type="email"
        name="email"
        value={formik.values.email}
        onChange={formik.handleChange}
      />
      <button type="submit">Submit</button>
    </form>
  );
};
