Is it possible to send a value in both [FromForm] and [FromHeader] with Refit

[cmgchess]

Hey,
I’m using refit with a multipart upload endpoint, and I’m running into an issue when trying to send the same value in both the form body (so it binds into my model) and as a custom header

Here is what I had tried

[ApiController]
[Route("api/foo")]
public class FooController : ControllerBase
{
    [HttpPost("upload")]
    public async Task<IActionResult> UploadAsync(
        IFormFile file,
        [FromForm] FooRequest request,
        [FromHeader(Name = "FooHeader")] long fooId
    )
    {
        return Ok(new
        {
            FromFormFooId = request.Foo,
            FromHeaderFooId = fooId
        });
    }
}

public class FooRequest
{
    public long Foo { get; set; }
    public string Description { get; set; }
}

public interface IFooApi
{
    [Post("/api/foo/upload")]
    [Multipart]
    Task<ApiResponse<string>> UploadAsync(
        [AliasAs("file")] StreamPart file,
        [AliasAs("foo")][Header("FooHeader")] long fooId,
        [AliasAs("description")] string description
    );
}

I did [AliasAs("foo")][Header("FooHeader")] long fooId, hoping it would bind it to both the FromForm and the Header.

What I observed from the controller was that I get the correct value in the Header, but the value coming from the FooRequest.Foo (from [FromForm]) is coming as 0. I was expecting both to have the same value.

This however worked when my Foo is a path param instead of [FromForm]

Any suggestions?

Thanks in advance 🙏
