Hello,

I need to add SAC on a queue.

My conf :

input {  
rabbitmq {  
...  
arguments =\> {"x-single-active-consumer" =\> true}  
#passive =\> true (SAC working by another way)  
}  
}

The warn :

[WARN] 2020-01-06 09:44:50.092 \<rabbitmq] rabbitmq - Error while setting up connection for rabbitmq input! Will retry. {:message=\>"#method\<channel.close\>(reply-code=406, reply-text=PRECONDITION\_FAILED - invalid arg 'x-single-active-consumer' for queue 'xxx' in vhost 'xxx': {unacceptable\_type,longstr}, class-id=50, method-id=10)", :class=\>"MarchHare::ChannelAlreadyClosed", :location=\>"/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/march\_hare-4.1.1-java/lib/march\_hare/exceptions.rb:121:in `convert\_and\_reraise'"}

And the queue is not created.

Input version : logstash-input-rabbitmq (6.0.4)

Any advice ?

Thx !
