贝宝退款API出现未经授权的错误

如何解决贝宝退款API出现未经授权的错误

 const { paymentId } = req.body;

const refundURI = `https://api.sandBox.paypal.com/v2/payments/captures/${paymentId}/refund`;
// get access token
const { access_token } = await generatetoken();
// console.log(JSON.stringify(access_token));

const refundObj = await Axios.post(refundURI,{
  headers: {
    Accept: `application/json`,Authorization: `Bearer ${access_token}`,},body: JSON.stringify({
    amount: {
      currency_code: "USD",value: "10.00",}),});

我正在尝试退还Paypal付款。我正在生成访问令牌，但仍未提供401状态码的授权。
