ASP.Net Core Web API MVC

Question

I'm a tad confused - I've created an ASP.Net Core Web API MVC Project and testing out a couple of the pre-implemented endpoints but consistently getting the following response "{"id":["The value 'values' is not valid."]}".

target url : https://url/api/values

namespace Project.Api.Controllers
{
    [Route("api)]
    [ApiController]
    public class ValuesController : ControllerBase
    {
        // GET api/values
        [HttpGet]
        public ActionResult<IEnumerable<string>> Get()
        {
            return new string[] { "value1", "value2" };
        }
    }
}

Any ideas? Thanks

Which endpoint are you calling? And could you show us just a bit more (relevant) code? The route by default is api/<RouterName> so you might be using an incorrect route. — rickvdbosch

please post the entire controller class as well as the RouteConfig. If you can include an example of the URI you are making a request to as well, that'd be great — GregH

The default project template works so there was either a change to it or you're not making a request to a valid route correctly- please post the relevant code so we can help — GregH

You have the [Route("api")] annotation on your controller so your Get method will be accessible at localhost:port/api instead of localhost:port/api/values.

If you change the annotation to [Route("api/[controller]")] then the current route you are requesting (localhost:port/api/values) will work
