Get callTranscript Content does not work in SDK

[MikeYeager]

Describe the bug

I am trying to download transcripts and recordings using Microsoft.Identity.Web.GraphServiceClient 2.18.1. The docs ?? say this:

// Code snippets are only available for the latest version. Current version is 5.x

// To initialize your graphClient, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=csharp
await graphClient.Users["{user-id}"].OnlineMeetings["{onlineMeeting-id}"].Transcripts["{callTranscript-id}"].Content.GetAsync();

Which should return a Task\<Stream> according to Intellisense. When I run this code, I get the following exception, Invalid format 'application/octet-stream, application/json' specified. with a 400 response code. If I remove .Content. I do get the transcript information.

Expected behavior

I would expect a stream to be returned with a 200 response. application/octet-stream would seem to be the correct content type for that.

How to reproduce

n/a

SDK Version

2.18.1

Latest version known to work for scenario above?

No response

Known Workarounds

I can download the transcript via postman if I specify the $format=text/vtt query parameter. Can't find a work-around within the SDK.

Thanks for raising this @MikeYeager

Are you able to share a sample URL that works via postman to help compare with what path the SDK is calling? Could you also share a link to the docs where the code snippet is from?

@andrueastman Sorry for the delay, was sidelined with BUILD. The docs can be found here: https://learn.microsoft.com/en-us/graph/api/calltranscript-get?view=graph-rest-1.0&tabs=csharp Check out Examples 2 & 3 (choose C#). In example 3 it mentions you can set requestConfiguration.QueryParameters.Format = "text/vtt", but no such parameter exists. I even tried setting a value for a QueryParameter with SetValue, but that doesn't work either.

I exported the PostMan call as a C# snippet. Notice it's sending a query param to return text/vtt.

var client = new HttpClient();
var request = new HttpRequestMessage(HttpMethod.Get, "https://graph.microsoft.com/v1.0/users/ce7d3c3d-6047-450e-b6fa-6603a4a0ecc4/onlineMeetings/MSo1ODNjNjg0Yy1kNGIyLTQ0MTQtYTFhYy05NjExOTgxMDc3MzkqMCoqMTk6bWVldGluZ19ORFpqWXpRM1pXVXROVE14WmkwME9XSXlMVGxpTkdFdFpHWTRaVE0yTldFNE9UTmhAdGhyZWFkLnYy/transcripts/MSMjMCMjODNmMjYxMjEtYTNmMi00ZDgzLWJkN2UtZGQzYTQwYmM0ZjU5/content?$format=text/vtt");
request.Headers.Add("Authorization", "Bearer eyJ0eXAiO ... n_w");
var response = await client.SendAsync(request);
response.EnsureSuccessStatusCode();
Console.WriteLine(await response.Content.ReadAsStringAsync());

This is caused by the metadata missing the $format parameter. Filed https://github.com/microsoftgraph/msgraph-metadata/issues/632
