Reproduction steps

Trying to perform a deployment to GKE using this pipeline:

pipeline {
    agent any
    environment {
        PROJECT_ID = 'my-google-cloud-project-id'
        CLUSTER_NAME = 'my-gke-cluster-name'
        LOCATION = 'us-central1-a'
        CREDENTIALS_ID = 'my-service-account-creds-id'
    }
    stages {
        stage('Deploy to GKE') {
            steps{
                step([
                        $class: 'KubernetesEngineBuilder',
                        projectId: env.PROJECT_ID,
                        clusterName: env.CLUSTER_NAME,
                        location: env.LOCATION,
                        manifestPattern: 'gke-deployment.yaml',
                        credentialsId: env.CREDENTIALS_ID,
                        verifyDeployments: true])
            }
        }
    }
}

Results

• Expected result:

The deployment works, with no stacktraces in the logs.

• Actual result:

The deployment works, the build succeeds, but there is the following stacktrace repeated in the logs:

Did you find any workaround to this?

No, I did not, but at the time I wasn't in a position to dig in to it either. I raised the bug and had to move on to something else.
