埋め込みPower BiレポートPromiseは定義されていませんpowerbi.js

Question

私はpower biレポートを作成しました。このレポートをMVCサイトに埋め込みたいのですが。ここに私のコードは次のとおりです。 - に「この」リダイレクトで

private static readonly string ClientID = ConfigurationManager.AppSettings["ClientID"]; 
private static readonly string ClientSecret = ConfigurationManager.AppSettings["ClientSecret"]; 
private static readonly string RedirectUrl = ConfigurationManager.AppSettings["RedirectUrl"]; 
private static readonly string AADAuthorityUri = ConfigurationManager.AppSettings["AADAuthorityUri"]; 
private static readonly string PowerBiAPI = ConfigurationManager.AppSettings["PowerBiAPI"]; 
private static readonly string PowerBiDataset = ConfigurationManager.AppSettings["PowerBiDataset"]; 
private static readonly string baseUri = PowerBiDataset; 
private static string accessToken = string.Empty; 

public string GetAccessToken(string authorizationCode, string clientID, string clientSecret, string redirectUri) 
     {  
      TokenCache TC = new TokenCache(); 
      string authority = AADAuthorityUri; 
      AuthenticationContext AC = new AuthenticationContext(authority, TC); 
      ClientCredential cc = new ClientCredential(clientID, clientSecret); 
      return AC.AcquireTokenByAuthorizationCodeAsync(
       authorizationCode, 
       new Uri(redirectUri), cc).Result.AccessToken; 
     } 

     public void GetAuthorizationCode() 
     { 
      var @params = new NameValueCollection 
      { 
       {"response_type", "code"}, 
       {"client_id", ClientID}, 
       {"resource", PowerBiAPI}, 
       { "redirect_uri", RedirectUrl} 
      }; 

      var queryString = HttpUtility.ParseQueryString(string.Empty); 
      queryString.Add(@params); 
      Response.Redirect(String.Format(AADAuthorityUri + "?{0}", queryString)); 
     } 

     public ActionResult Index() 
     { 
      if (Request.QueryString["code"] != null) 
      { 
       Session["AccessToken"] = GetAccessToken(
        HttpContext.Request["code"], 
        ClientID, 
        ClientSecret, 
        RedirectUrl); 
      } 
      if (Session["AccessToken"] != null) 
      { 
       accessToken = Session["AccessToken"].ToString(); 
       System.Net.WebRequest request = System.Net.WebRequest.Create(
       String.Format("{0}/Reports", 
       baseUri)) as System.Net.HttpWebRequest; 

       request.Method = "GET"; 
       request.ContentLength = 0; 
       request.Headers.Add("Authorization", String.Format("Bearer {0}", accessToken)); 
       using (var response = request.GetResponse() as System.Net.HttpWebResponse) 
       { 
        using (var reader = new System.IO.StreamReader(response.GetResponseStream())) 
        { 
         PBIReports Reports = JsonConvert.DeserializeObject<PBIReports>(reader.ReadToEnd()); 
         if (Reports.value.Length > 0) 
         { 
          PBIReport report = Reports.value[13]; 
          return View(report); 
         } 
        } 
       } 
      } 
      GetAuthorizationCode(); 
      return View(); 
     } 

、それは電源バイログインページのために行くと、私はそれに署名した後、このページに戻ってリダイレクトする（ホームページなどしてURLをリダイレクト同じです）。すべてのレポートデータを取得した後、いくつかの時間後に、エラーメッセージは、それが

Exception was thrown at line 1236, column 335 in https://app.powerbi.com/13.0.1781.272/scripts/powerbiportal.dependencies.externals.bundle.min.js 

0x80070005 - JavaScript runtime error: Access is denied. 

If there is a handler for this exception, the program may be safely continued. 

Exception was thrown at line 42, column 17057 in https://app.powerbi.com/13.0.1781.272/scripts/powerbiportal.common.bundle.min.js 

0x80070005 - JavaScript runtime error: Access is denied. 

If there is a handler for this exception, the program may be safely continued. 

を言うし、再びそれが再び最初のエラーメッセージを表示開始した後Unhandled exception at line 5153, column 11 in http://localhost:34244/Scripts/powerbi.js 0x800a1391 - JavaScript runtime error: 'Promise' is undefined

を言ってアップします。

は、ここではまだ約束をサポートしていない私のindex.cshtml

    ViewBag.Title = "Index"; 
    Layout = "~/Views/Shared/_ColumnsOne.cshtml";

    window.onload = function() { 
     var accessToken = "@Session["AccessToken"].ToString()"; 

     if (!accessToken || accessToken == "") 
     { 
      return; 
     } 

     var embedUrl = "@Model.embedUrl"; 
     var reportId = "@Model.id"; 

     var config = { 
      type: 'report', 
      accessToken: accessToken,

      settings: {

     const filter = {

      }, 
      operator: "In", 
      values: ["10"] 
     }; 
     var reportContainer = document.getElementById('reportContainer'); 


     var report = powerbi.embed(reportContainer, config); 

     report.on("loaded", function() { 
      var logView = document.getElementById('logView'); 
      logView.innerHTML = logView.innerHTML + "Loaded<br/>"; 

      report.off("loaded");

     report.on("rendered", function() { 
      var logView = document.getElementById('logView'); 
      logView.innerHTML = logView.innerHTML + "Rendered<br/>"; 

      report.off("rendered"); 
     }); 
     report.setFilters([filter]) 
     .then(function (result) { 
      Log.log(result); 
     }) 
     .catch(function (errors) {

IEです。外部ライブラリを含めることでサポートを有効にすることができます。こちらのPower BIに関するMicrosoftのコメントを参照してください。Support for IE8 and Promises?

IE11で同じ問題が発生しました。それがあなたにも役立つことを願っています。
