angular - Error occuring while reading json file in angular2 -


i trying read config.json file in angular2 service below-

load() {     return new promise((resolve, reject) => {         this.http.get('./config.json')             .map(res => res.json())             .subscribe((env_data) => {                 console.log('env_data: ' + env_data);                 this._env = env_data;                 }); }

this contains list of key , value pairs of application configuration settings. structure of config.json file this-

{   "env": "development" }

but, on calling load method of angular2 service, receiving below error-
