问题
Axios无法按照预期处理500错误。按照Axios错误处理提供的方式进行，但并不起作用。
POST请求发送用户名/电子邮件和密码，但密码故意设置为不正确，以测试错误处理。如果设置了正确的密码，则可以正常工作。
axios.post(
config.apiGateway.URL + ".../signin",
payload
).then(response => {
console.log(response)
if(response.status == 200){
console.log("Login successfull");
this.setState({token: response.data.JWT_TOKEN});
} else {
console.log(response.status)
this.setError()
}
}).catch(error => {
this.setError()
console.log(error)
if (error.response) {
console.log("--------------------------------------------------")
// The request was made and the server responded with a status code
// that falls out of the range of 2xx
console.log(error.response.data);
console.log(error.response.status);
console.log(error.response.headers);
} else if (error.request) {
console.log("*************************")
// The request was made but no response was received
// `error.request` is an instance of XMLHttpRequest in the browser and an instance of
// http.ClientRequest in node.js
console.log(error.request);
} else {
console.log("++++++++++++++++++++++++")
// Something happened in setting up the request that triggered an Error
console.log('Error', error.message);
}
console.log(error.config);
})
结果
预期执行 if (error.response) 部分，但实际执行的是 else if (error.request)。
Access to XMLHttpRequest at 'https://***-api.us-east-1.amazonaws.com/dev/***/signin' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

在Chrome开发者工具中，OPTIONS方法返回如下的200状态码。

POST方法按预期返回500。
Request Method: POST
Status Code: 500

环境
使用axios 0.18.0、Google Chrome 70.0.3538.77在Ubuntu 18 LTS中。
问题
请建议如何正确处理500错误。
研究
如何在Redux / Axios中捕获和处理422错误响应？看起来与错误被设置为堆栈跟踪以及响应似乎没有被填充的相同问题。
编辑： 我仍然不明白为什么记录错误会返回那个堆栈消息。我尝试像这样记录它。然后你可以看到它是一个对象。
