Don't hand to the JsonResult of the Microsoft.AspNetCore.Mvc namespace stringified JSON in C#.

When you parse the string in JS you may get a string for the object instead of an object. This for example is bad. Instead, do stuff like this:

1. context.Result = new JsonResult(new { Message = context.Exception.Message });
    
2. string message = "An error at the API occurred. The specific error message is
         being hidden from what the API exposes for security. If you have access to the
         logs you may see a better description free from obfuscation therein.";
   context.Result = new JsonResult(new { Message = message });
