We are using both scripted and declarative jenkins pipeline and using dynamic ecs agent for slave.

Following is the configuration :

ecsTaskTemplate(
    inheritFrom: dynamiclabelNp
    overrides: [],   
    taskDefinitionOverride: "arn:aws:redacted:redacted:task-definition/td:9"
) {
  node(dynamiclabelNp) {
    stage("I dunno why you say goodbye"){
      sh 'echo hello'
    }
  }
}

And for declarative pipeline:

pipeline {
  agent none

  stages {
    stage('Test') {
        agent {
            ecs {
                inheritFrom dynamiclabelNp,
overrides: [],   
        taskDefinitionOverride: "arn:aws:redacted:redacted:task-definition/td:9"          
            }
        }
        steps {
            sh 'echo hello'
        }
    }
  }
}

Now for declarative pipeline the node is coming up with a random name and picking the above task definition. But for scripted it is showing all node in label “dynamic-agent-test” is offline and if I see the logs it shows that task definition (arn:aws:redacted:redacted:task-definition/td:7) does not exist, which is a old task definition.

How to resolve this for scripted pipeline.
