I have a Native App. I am trying to Embed (App Owns Data) power bi content to my Native App. I am trying to embed a report/ dashboard. To do so I have to generate the Embed Token. When I try to generate the embed token it gives me 500 internal Server error or Forbidden status. Please see the attached error information. What could the reason for this error ? Is this because of Access issue?

 

 

Below is my code:

public async Task<ActionResult> GetReportByID(String Id)
{

var error = GetWebConfigErrors();
if (error != null)
{
return View(new EmbedConfig()
{
ErrorMessage = error
});
}

// Create a user password cradentials.
var credential = new UserPasswordCredential(Username, Password);

// Authenticate using created credentials
var authenticationContext = new AuthenticationContext(AuthorityUrl);
var authenticationResult = await authenticationContext.AcquireTokenAsync(ResourceUrl, ClientId, credential);

if (authenticationResult == null)
{
return View(new EmbedConfig()
{
ErrorMessage = "Authentication Failed."
});
}

var tokenCredentials = new TokenCredentials(authenticationResult.AccessToken, "Bearer");

// Create a Power BI Client object. It will be used to call Power BI APIs.
using (var client = new PowerBIClient(new Uri(ApiUrl), tokenCredentials))
{
// Get a list of reports.
var reports = await client.Reports.GetReportsInGroupAsync(GroupId);

var report = reports.Value.FirstOrDefault();
// Get the first report in the group.
foreach (var item in reports.Value)
{
if (Id == item.Id)
{
report = item;
}
}

if (report == null)
{
return View(new EmbedConfig()
{
ErrorMessage = "Group has no reports."
});
}


// Generate Embed Token.
var generateTokenRequestParameters = new GenerateTokenRequest(accessLevel: "view");
var tokenResponse = await client.Reports.GenerateTokenInGroupAsync(GroupId, Id, generateTokenRequestParameters);

if (tokenResponse == null)
{
return View(new EmbedConfig()
{
ErrorMessage = "Failed to generate embed token."
});
}

// Generate Embed Configuration.
var embedConfig = new EmbedConfig()
{
EmbedToken = tokenResponse,
EmbedUrl = report.EmbedUrl,
Id = report.Id
};

return View(embedConfig);
}

}

The above code works in my test. Usually Forbidden error indicates the registered app doesn't have suffiecient permission, please check premissions in azure portal. For other issues, to have a better troubleshooting, please add try..catch block to get more detailed error information.

                try
                {
                    // Generate Embed Token.
                    var generateTokenRequestParameters = new GenerateTokenRequest(accessLevel: "view");
                    var  tokenResponse = await client.Reports.GenerateTokenInGroupAsync(GroupId, report.Id, generateTokenRequestParameters);

                    if (tokenResponse == null)
                    {
                        return View(new EmbedConfig()
                        {
                            ErrorMessage = "Failed to generate embed token."
                        });
                    }

                    // Generate Embed Configuration.
                    var embedConfig = new EmbedConfig()
                    {
                        EmbedToken = tokenResponse,
                        EmbedUrl = report.EmbedUrl,
                        Id = report.Id
                    };

                    return View(embedConfig);
                }

                catch (HttpOperationException ex)
                {
                    //debug content for error details

                    var content = ex.Response.Content; 
                }

By the way, when playing with Power BI API lib, I'd like to test the correlated rest api(GenerateToken in this case) with Postman at first.
