request may not have attr exception

[Germey]

request may not have attr exception, I've tested for many times.

if request doesn't have exception attr, it will not call exception_handler, and at this time, response is none, so you don't know where to handle this situation.

So although request doesn't have exception attr, you can still call exception handler, so you can handle this situation by judgeing request's attrs.

Thank you for this contribution @Germey and apologies for the very long delay in getting this addressed.

This makes perfect sense to me. If there is no response, clearly it's an exceptional case and the exception handler should have an opportunity to handle it, even if the exception attr doesn't exist.

I'll go ahead and merge this in and release a new version Though, I am curious if you have any example of how the issue can be reproduced so that tests can be added.

Thanks again!

Thanks for your merging. But I forgot the example because of so long time. If I have similar case, I'll send it back to you. Hopes well, Thanks.
