Fails to generate application/xml return value 201 for post (application/json works)

[mawess]

What are you generating using Kiota, clients or plugins?

API Client/SDK

In what context or format are you using Kiota?

Nuget tool

Client library/SDK language

Csharp

Describe the bug

I specify the returned data type of POST on resource /post as application/xml but the generated GetAsync just returns Task.

Expected behavior

Generated function PostAsync should return Task

How to reproduce

Download and expand the zip file, generate the client (generate.bat) and then inspect PostAsync in Client/Post/PostRequestBuilder.cs XmlBug.zip

Hint: use the info command to get the list of dependencies you need to add to your project.
Example: kiota info -d "C:\Users\mats.wessling\source\repos\XmlBug\XmlBug.\PostBug.yml" -l CSharp

Hint: use the --include-path and --exclude-path options with glob patterns to filter the paths generated.
Example: kiota generate --include-path "**/foo" -d "C:\Users\mats.wessling\source\repos\XmlBug\XmlBug.\PostBug.yml"

Hi @mawess
Thank you for using kiota and for reaching out.

Passing -m "application/xml" should solve your generation issue. more information
