Best Practices for Working with Stream Responses?

[chrstophr-wltrs]

I have a few endpoints that return byte[], and I was wondering about best practices for working with those.

Let's say I have some interface:

public interface ISignature
{
	[Get("/signature")]
	Task<IApiResponse<byte[]>> GetDoc();
}

When I attempt to run tests with this client, I run into a few snags.

/* As part of a [Test] method */
var response = await _api.GetDoc();
Assert.That(response.IsSuccessStatusCode);

/* This fails, even though the endpoint is working exactly as expected */
Assert.That(response.Error, Is.Null);

I can execute the request, but Refit (by default) tries to deserialize the response into JSON, which of course does not work.

Refit Error: System.Text.Json.JsonException
	'test' is an invalid JSON literal. Expected the literal 'true'. Path: $ | LineNumber: 0 | BytePositionInLine: 1.

Of course, I came across this older issue, but I wanted to see if this was still up to date.

What are the recommendations for telling Refit that the response body should not be parsed as JSON?
