error.response is undefined if axios request fails










0















I cannot access the error (response) status code if an axios request has failed in my Vue.js app. I cannot figure out why the response is undefined in both '.catch' and 'axios.interceptors.response'. I followed this instruction that demonstrates that 'error.response' can be easily accessed with a code like this:



axios.interceptors.response.use(
(response) =>
console.log(response);
return response;
,
(error) =>
handleApiFail(error.response);
);


If I add this code to 'main.js' in my app, 'handleApiFail' is called when a request fails, but error.response is undefined in the second lambda and the first lambda is not called. If a request succeeded the 'response' in the first lambda is defined and has the status code.



EDIT1: this is not an option because my OPTIONS requests do not require authorization. Also there are various posts describing the same situation.

          This is an idiosyncrasy of axios. A quick solution to this is to serialize the response:



          JSON.stringify(error)


          Please refer to this GitHub issue for more info: https://github.com/axios/axios/issues/960



          As someone pointed out there, you can check the error status code in the action and run some other commit depending on it.

            Check the discussion on GitHub, looks like either axios or vuex (or maybe both) are mangling the error response. The trick (as you pointed out as well) is to JSON.stringify and then JSON.parse the error. Just try that and you should be able to see the actual error response

            I'm afraid I can't help much further as I'm not familiar with Vuex, but you might be able to find the solution on the GitHub discussion. They labeled it as a non-issue and closed it, but people are still commenting there.

          The lack of



          access-control-allow-origin: *


          header in the response caused the browser to block my request.



          Adding the header makes axios work fine.
