                                        );

        return waitAndRetryPolicy.WrapAsync(circuitBreakerPolicy);

if i use my custom exception, My retry fails after logging .Breaker logging: Breaking the circuit for 10000ms!

It works fine if i use the ;default exception retry works after circuitbreak till it is closed
