Angular 19 HTTP request to .NET Core 8

I create a .NET Core Angular template project in Visual Studio 2022 which has a controller named "Weather forecast". All HTTP requests to this controller work properly but the similar HTTP request to my new controller doesn't work.

I even add this line to my proxy.config.js:

context:[
"weatherforecast",
"/test"
]


My controller code:

[ApiController]
[Route("[controller]")]
public class TestController : ControllerBase
{
[HttpPost]
public IActionResult Post()
{
return new JsonResult("Hello Test Post");
}
}


My Angular function:

test() {
http.post('/test', {}).subscribe(
(result) => {
console.log(result);
}
);
}
