Jenkins Scripted Pipeline: Groovy if statement

I can't seem to get the variable glooNamespaceExists to actually print.I see in the console the response from kubectl is there but the variable seems to be null - I'm looking to skip this entire build stage if the namespace already exists..

    stage('Setup Gloo Ingress Controller') {
      def glooNamespaceExists = sh(script: "kubectl get ns gloo-system -o jsonpath='{.status.phase}'")

      if (glooNamespaceExists != 'Active') {
        sh 'helm repo add gloo https://storage.googleapis.com/solo-public-helm'
        sh 'helm repo update'
        sh 'kubectl create namespace gloo-system'
        sh 'helm install gloo gloo/gloo --namespace gloo-system'
      }
    }

EDIT: Console output of run:

[Pipeline] { (Setup Gloo Ingress Controller)
[Pipeline] sh
+ kubectl get ns gloo-system -o jsonpath={.status.phase}
Active
[Pipeline] sh
+ helm repo add gloo https://storage.googleapis.com/solo-public-helm

Please add returnStdout: true to your script command which will return exact output. Otherwise it will return status code which 0. Please add returnStdout: true like this so your command should be like this,

def glooNamespaceExists = sh(script: "kubectl get ns gloo-system -o jsonpath='{.status.phase}'", returnStdout: true)
