I am trying to build Elasticsearch Angular app. I am using require.js.

main.js

* * *

require.config({

```
paths : {
    'angular' : '../bower_components/angular/angular',
    'elasticsearch' : '../bower_components/elasticsearch/elasticsearch',
    'app' : 'app',
    'coreModule':'coreModule',
    'esClient' : 'service/esClient'
},

shim : {
    
    'app':{
        'deps' : ['angular','coreModule']
    },
    
    'coreModule' : {
        'deps' :['angular', 'elasticsearch','esClient']   
    },
    
    'esClient' : {
        'deps' :['angular', 'elasticsearch']   
    }
    
}

```

});

require(['app'], function(){

angular.bootstrap(document, ['app']);  
});

* * *

esClient.js

* * *

define(function(){

```
var esClient=angular.module('esClient', ['elasticsearch']);

esClient.service('client', function (esFactory) {
	return esFactory({
		host: 'http://localhost:9200',
		apiVersion: '1.5',
		log: 'trace'
	});
});

```

});

* * *

But it is throwing the following errors. Anyone else faced this issue?
