使用JWT授权流请求访问令牌的NodeJS DocuSign返回invalid_request

const jwt = require('jsonwebtoken');
const request = require('request');

const payload = {
  // 添加所需的令牌信息，例如用户ID、角色等
  userId: '123456',
  role: 'admin'
};

const secretKey = 'your-secret-key'; // 用于签名的密钥

const token = jwt.sign(payload, secretKey);

const options = {
  url: 'https://api.example.com/endpoint',
  headers: {
    Authorization: `Bearer ${token}` // 将JWT令牌添加到请求头中
  }
};

request(options, (error, response, body) => {
  if (error) {
    console.error(error);
  } else {
    console.log(body);
  }
});
