Describe the bug 🐞

A bug happened!

I have an API that returns a problem details when supplied inputs fail validation

I have a razor page application using the refit library to make api calls.

When the application posts data with invalid inputs an ApiException is caught, but not a ValidationApiException. If the ApiException has a content type "application/problem+json", a ValidationApiException should be thrown?

Step to reproduce

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Reproduction repository

Expected behavior

This should happen...

A ValidationException should be thrown with a content type application/problem+json

Hey, could you share a minimal reproduction of this issue? I haven't been able to reproduce in a modern ASP project.

I'm guessing your issue is related to this line in ApiException, I'm guessing the returned header in your example is being recognized by Refit.

if (
    response
        .Content.Headers?.ContentType
        ?.MediaType
        ?.Equals("application/problem+json") ?? false
)
{
    exception = ValidationApiException.Create(exception);
}
