hi
RabbitMQ 3.13.2Erlang 26.2.5
go 1.22
os : linux 3.10.0-1160.45.1.el7.x86_64 #1 SMP Wed Oct 13 17:20:51 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
package : github.com/rabbitmq/amqp091-go v1.10.0

in our code we got signal with error nil
what should we do at this time?is this error fake?

golang code :

errNotifyClose := <-conn.NotifyClose(make(chan *amqp.Error))
		if !StopApp {
			myerrror := fmt.Sprintf("CunsumerStart disconnect signal error %#v", errNotifyClose)
		}

error code :

 signal error (*amqp091.Error)(nil)
