Bot never joins Team Meeting: Server Internal Error. DiagCode: 500#1203003.@

[aliasmac]

Describe the issue

When inviting the bot to a Teams call we receive a HTTP 500 error and the bot never joins the call.

Code Snippet

var statefulCall = await this.Client.Calls().AddAsync(joinParams).ConfigureAwait(false);

This runs successfully, but we never receive the established callback.

Expected behavior

We expect to receive a series of callbacks from Microsoft. We expect to receive the established callback that eventually resolves to the Bot joining a Teams call.

Additional context

• We have already setup the bot to run as a single instance, with this we're trying to run multiple instances. The implementation of the k8s infra takes inspiration from this setup.
• We're running this on AWS, we'll soon be moving to Azure as was recommended to my colleague a little while ago here
• The Bot has never joined the call with this setup

I encounter the same issue in a different environment:
#772

[InDieTasten]

Can you confirm that the media platform part of your bot was able to initialize successfully? I think it would help if you could provide the GraphLogger output of the SDK initialization and logs during the join attempt, ideally in a spoiler

Like this

Hey @InDieTasten thanks for the tip, adding the logging revealed the root cause which we were able to fix, wasn't aware we could add the logger to the media platform, thanks!

[csk-bsi]

Hey, could you describe your root cause? I may face the same issue: #772

Thanks!

[aliasmac]

@csk-bsi it was the most innocuous error, we were passing env variables via the k8s manifest for the different port mappings and since we're using .NET it expects a specific formatting which we got wrong for the public port, so instead of using the port we were exposing on our LB it was using a hardcoded port on our appsetting.json!

Hey @aliasmac, if you're dealing with issues where a bot never joins a Teams meeting due to server errors, you might want to check out the Recall.ai API.

It’s a simple 3rd party API that lets you use meeting bots to join meetings and capture raw audio/video/metadata without needing to build, scale, and maintain these bots yourself.

Here are the API docs: https://docs.recall.ai
