Generate an 400 Bad Request (or any status code) with custom detail from a Service

[blogcraft]

If inside of a controller I return a StatusCode(400, "You missed something")

I will get a ProblemDetails object with a detail property with value "You missed something".

But most of my business logic is inside services. Is there any way to throw some kind of custom exception that generates a ProblemDetail object with the detail value in production? So I can show to the client user a readable reason of the failure?

Thanks

Hey @blogcraft! 👋🏻

Is there any way to throw some kind of custom exception that generates a ProblemDetail object with the detail value in production?

Sure, you could just define your own exception type (or use some existing type) and configure its mapping to a ProblemDetails instance:

services.AddProblemDetails(x =>
{
    x.Map<MyCustomException>((ctx, ex) => /* return your problem details instance here */); 
});
