      Description

      Issue

      When a kubernetes agent is spun up to fulfil a node step (not a podTemplate step nor kubernetes}) declarative directive), certain failure to create pods would cause a {{NullPointerException in the logs:

      2021-07-05 06:33:32.815+0000 [id=2910]	WARNING	o.c.j.p.k.KubernetesLauncher#launch: Error in provisioning; agent=KubernetesSlave name: default-java-fbmpk, template=PodTemplate{id='9828c91f-e185-4d4a-8d92-6a88733fd6e2', name='default-java', label='default-java'}

      How to Reproduce

      • Create a Kubernetes Pod template globally, with label "default-java"
      • Create a pipeline like the following
      node ('default-java') {
          echo "OK"
      }
      
      • Revoke the pod/create permission for the ServiceAccount used to deploy the pod (this is one example scenario that would fall into that condition, there might be other)
      • Start the pipeline

      The pipeline fails (expected) and the Jenkins logs show the NPE.
