Hi @Snoopy_hu ,

Have you enabled the subscribtion in basic information and  can you please add debug logger to find whether the alert subscribtion isrunning at time of main alert.

Thanks & Regards,

Hi.@Arun_C

Yes, I've started the subscription and added the error alerts at the same time, but the error alerts really don't take effect when the subscription is triggered.
