I am using Postman for the first time to POST to a server. I get an error `a non-descript body is required`.

What should I put in the body? I selected JSON and raw.

This is the Angular controller code:

```
namespace backend.Controllers
{
[Route("api/[controller]")]
[ApiController]
public class QuestionsController : ControllerBase
{
    // POST api/values
    [HttpPost]
    public void Post([FromBody] string value)
    {
    }
}

}

```
