Exception Midleware

[rpimentaf]

Hi! I'm facing a situation that I do not know if it is a bug or my mistake...
In a repository I throw a new exception in order to control configurations issues in the API. When I do this, a Try/Catch in the resolver catches the exception and, at that moment, I throw that exception (without the new keyword, subbmitting it to a higher level). The ackward situation is that the Exception Midleware do not capture it and the execution returns to the point the exception was initially thrown.
Is this correct? Or I'm doing anything wrong?
Tks!
