Problems with execution aws command via ssh jenkins

Good morning, how are you?

I have a problem with one execution via ssh in my jenkins.

Those characters that appear before did not appear, and we have not changed anything in the node..

The code we use is:

    withCredentials([usernamePassword(credentialsId: 'id', passwordVariable: 'pass', usernameVariable: 'user')]) {
        
                                def remote = [:]
                                remote.name = 'id_nme'
                                remote.host = 'ip_node'
                                remote.user = user
                                remote.password = pass
                                remote.allowAnyHosts = true
                                remote.timeoutSec = 300
        
        sshCommand remote: remote, command: "aws autoscaling describe-auto-scaling-groups --auto-scaling-group-name [name_asg]"

}

When the command is launched, the job is stuck and does not progress.
