Odata 8.0.6 not working for get request with a key value

So I recently upgraded to odata version 8.0.6 from version 7. In the new version we don't have the ODataRoutePrefixAttribute and ODataRouteAttribute. So i was using [Route] to map to controller.

[Authorize]
[Route("v1/students")]
public class StudentController : ODataController
{
    [HttpGet("({key)")]
    [EnableQuery]
    public async Task<Student> Get([FromODataUri] long key)
    {
        return await _studentRepository.GetStudentByIdAsync(key);
    }

}

public static IEdmModel GetEdmModel()
 { 
  ODataModelBuilder builder = new ODataConventionModelBuilder(); 
  builder.EntitySet<Student>("Students"); 
  return builder.GetEdmModel(); 
 }

When i am hitting url with https://localhost:5001/v1/student(2) it is working fine because it is convention odata routing but when i am doing attribute based routing and hit url https://localhost:5001/v1/students(2) it give me error 404 not found, when i am doing https://localhost:5001/v1/students/(2) it is giving response. But this action method is non odata endpoint. I am not understanding why this issue is happening.
