SetMediaPlatformSettings() Failed with SEHException

[KanaHayama]

Describe the issue
The Media Platform fails to initialize, causing the entire application to halt.

Code Snippet

/* Build client */
var builder = new CommunicationsClientBuilder(_appOptions.Value.Name, _appOptions.Value.Id, _graphLogger);
builder.SetAuthenticationProvider(_authProvider);
Debug.Assert(!string.IsNullOrEmpty(_options.Value.NotificationUrl));
builder.SetNotificationUrl(new Uri(_options.Value.NotificationUrl));
Debug.Assert(!string.IsNullOrWhiteSpace(_options.Value.CertificateThumbprint));
var certificate = GetCertificate(_options.Value.CertificateThumbprint);
var mediaPlatformSettings = new MediaPlatformSettings() {
    MediaPlatformInstanceSettings = new() {
        Certificate = certificate,
        InstanceInternalPort = _options.Value.InstanceInternalPort,
        InstancePublicIPAddress = IPAddress.Any,
        InstancePublicPort = _options.Value.InstancePublicPort,
        ServiceFqdn = _options.Value.ServiceFqdn,
    },
    ApplicationId = _appOptions.Value.Id,
    MediaPlatformLogger = _mediaPlatformLogger,
};
builder.SetMediaPlatformSettings(mediaPlatformSettings);
builder.SetServiceBaseUrl(new Uri(PlaceCallEndpointUrl));
_clinet = builder.Build();
_clinet.OnNotificationQueued += OnNotificationQueued;
_clinet.OnNotificationProcessed += OnNotificationProcessed;
_clinet.OnNotificationException += OnNotificationException;

Expected behavior
Execute without error.

Additional context
I am resuming an old project that was running well a year ago. It uses .NET 8.0 with Microsoft.Skype.Bots.Media version 1.27.0.2-alpha, together with Microsoft.Graph.Communications packages version 1.2.0.10563.
A couple of days ago, when I ran the project as is, I found that the ASP.NET Core server launched successfully, including the Media Platform, but when I requested the bot to join a meeting, an SEHException was thrown. The exception looks like this:

[17:24:11 DBG] Joining a meeting at https://teams.microsoft.com/l/meetup-join/***. This call will have a scenario ID of ***-***-***-***-***. <s:***.***.Services.BotServices.BotService>

   at Microsoft.Skype.Bots.Media.MPAzureAppHostWrapper.GetMediaStackClientEcsSettings() <s:***.***.MediaPlatformLogger>

So, I thought the SDK might have changed, so I updated to the versions listed in the previous section. Nothing else was changed, and I ran it again, but this time my ASP.NET Core server failed to launch. The problem occurred around the SetMediaPlatformSettings() call. I’ve included its log in a previous section. I tried several intermediate versions as well — the error behavior varied, but none of them succeeded. I can see that all these failures encountered an error in CreateEngineApiInstance(), but no details were provided, so I’m not sure what went wrong. I am running my server app with Admin privileges, and the internal port is not in use. Ngrok TCP tunnel is used. Please help, thank you!

Hi @owennewo, thank you for your reply. My project is using the latest NuGet version (1.31.0.225-preview), and none of the previous or current versions work.
If this problem only occurs in my project, I hope that in the next version of the SDK, this kind of error message can be made more explicit so that I can understand the exact error it encounters.

[ssulzer]

@KanaHayama are you encountering these errors on a bot deployed in a VM in Azure, or running locally on a dev machine/laptop?

My first thought would be to double check that you have the latest VC++ x64 runtime installed, but it looks like you do:

• C++ Redistributable: x64 14.44.35211

but possibly it is worth reinstalling the VC++ runtime to be certain.

If you are encountering this on a local machine, can you please try running on a VM in Azure - or a machine which has not run Teams (or Skype). Thanks.

[ssulzer]

Another question: Is the bot running in a container? If so, what is the base image?
Windows Server Core is not supported; the bot media SDK requires a full Windows Server image.
Thanks.

[KanaHayama]

Hi @ssulzer, I'm running it on my local Windows 11 Pro 24H2 desktop behind NAT, with an ngrok TCP tunnel launched before starting the web server application. I reinstalled the VC++ redistributable, but that didn’t help. Also, I’m not running the Teams client on my machine, since the error occurs during the application startup stage — the Teams client isn’t involved at that point.

I don’t have a VM in Azure right now, but I tested another laptop running Windows 11 Enterprise 23H2 and didn’t encounter any issues when launching my ASP.NET Core app there, although I did see two error messages from the Media Platform (log attached at the end). However, I couldn’t test the full meeting-joining feature that had previously worked because I noticed the copied meeting URL format had changed, so my app couldn't parse the meeting information from it, and I currently don’t know how to handle it. Since the application launched on this laptop, there may be some problems related to my development desktop, although I’m not sure whether the OS version made a difference.

Thank you for your help — you may close this issue. I’ll later try to see if I can find any clues on how to handle the new meeting URL format from the samples here.

Btw, I was launching the project directly from Visual Studio 2022. I am not using a container.

[ssulzer]

@KanaHayama A last-ditch effort to check: is the project configured to run in x64 mode? (use x64 and not AnyCPU or x86.)
Also try running with Administrator privileges (although I don't think that will make a difference).

The use of Windows 11 Pro vs. Enterprise edition shouldn't matter - assuming you are not running Windows 11 "N" or "KN" editions.

Those errors you saw in the startup logs about DynamicCapacity and MPCapacity can be ignored. Our next SDK release should resolve those.

[KanaHayama]

Yes, I am using the x64 platform. However, the Visual Studio solution platform is set to AnyCPU (I noticed that my projects do not have a <Platforms>x64</Platforms> element). Given my project settings (pasted below), it should still run in x64 mode. Adding this element and running again does not help. My laptop uses the same VS solution platform, and it runs without error there. This project used to work a year ago, so it should be running in x64 mode.

My Windows version does not contain the letter “N” in it. I am running my application with administrator privileges because it acquires the certificate from the local machine certificate store. I enforce this by specifying the requirement in my app.manifest file. I am using Kestrel directly, not IIS or IIS Express. I save my Kestrel settings in a separate file, since I found that the Media Platform starts another Kestrel instance that reads my web app’s appsettings.json file by default. So, Media Platform's Kestrel settings are in default. I am using \psi, but my projects were written from scratch, so it is not related to the Psi demo here.

Please note, we just released the next media SDK update -
https://www.nuget.org/packages/Microsoft.Skype.Bots.Media/1.32.0.70-preview

I'm not aware of anything in it that would address a crash inside the core media engine initialization (during CreateEngineApiInstance) but maybe worth trying.

[KanaHayama]

Hi @ssulzer, thank you for letting me know the new version. I tried it, and I still have the same issue. Here is an excerpt of the log:

While updating, there was a version conflict with the System.Diagnostics.PerformanceCounter package, so I updated it to version 9.0.9. Nothing else was changed.

I will develop on my laptop and start to handle the Teams meeting URL format issue, and come back to this issue after that. If you want, you may close this issue at any time. Thank you for your help!

[ssulzer]

I'll keep this issue open, as it seems others may have also encountered the same problem. We'd like to root cause it.
What we will probably need is a mini crash dump shared with us which captures the native exception that occurs within the CreateEngineApiInstance call.
