axios instance not hitting both request and response interceptor

Question

My axios instance is only hitting either the request interceptor or the response but not both. Take the following as an example.

const axiosInstance = axios.create({
    baseURL: GATEWAY_URL,
    headers: getDefaultHeaders(),
});

axiosInstance.interceptors.request.use(
    function (config) {
        console.log('before');
        return config;
    },
    function (error) {
        return Promise.reject(error);
    },
);

axiosInstance.interceptors.response.use(function (response) {
    console.log('after')
    return response;
  }, function (error) {
    return Promise.reject(error);
  });

I am getting before in the console. if I comment out the request interceptor then the response one logs.

Any ideas why?
