[Bug]: Body is null when function is hosted in Azure Isolated Worker

[JSCProjects]

Describe the bug 🐞

We are hosting some http functions in our Azure Isolated Worker and if we only add the Body attribute to our interface method. f.e.

public interface IClient
{
  [Post("/do-something/{id}")]
  Task<IApiResponse> DoSomething(string id, [Body] PostData data);  
}

The HttpRequestData.Body is always null. The only way we get it working is to add buffered: true. f.e.

public interface IClient
{
  [Post("/do-something/{id}")]
  Task<IApiResponse> DoSomething(string id, [Body(buffered: true)] PostData data);  
}

I've also seen this bug and maybe it's related.

Thanx in advance.

Greetz,

Add buffered: true does the trick for me in interface.
