HttpClient returns data with default values (Blazor)-CodePudding

I have the Blazor WASM application (dotnet 6). I can't get the data from the api controller. The call hits the controller method. HttpClient receives a response, the status is OK, but the returned data has default values. Can you please advise me what I'm doing wrong?

What am I doing wrong? Thank you

// Controller:
[ApiController]
[Route("test")]
public class TestController : ControllerBase
{
    [HttpGet]
    [Route("data")]
    [ProducesResponseType(typeof(TestStruc), StatusCodes.Status200OK)]
    public async Task<IActionResult> GetTest()
    {
        var data = new TestStruc();
        data.Id = 7;
        data.IsUse = true;
        data.Path = "root/bin/item";

        await Task.Delay(10); // instead of async query on db

        return HttpApiRep.Ok(data);
    }
}

// Blazor:
var res = await Http.GetAsync("test/data");
// res.StatusCode - Status code is OK
var data = await res.Content.ReadFromJsonAsync<TestStruc>();
// data have default values

// Data structure
public class TestStruc
{
    public int Id { get; set; } = 0;
    public bool IsUse { get; set; } = false;
    public string Path { get; set; } = "";
}

Update:

If I call await res.Content.ReadAsStringAsync(), I'll get:

{"data":{"id":7,"isUse":true,"path":"root/bin/item"},"status":"ok","errorCode":"undefined","errorMessage":"","isOk":true}

But when I call await res.Content.ReadFromJsonAsync<TestStruc> (), I get an object with default values.

Maybe a problem with deserialization?

Try this:

var _testStruc = await Http.GetFromJsonAsync<TestStruc>("test/data");

What is HttpApiRep ? I think it wraps your return.

This should work:

//return HttpApiRep.Ok(data);
  return Ok(data);
