argo workflow submit error - duplicated node name

Question

I am trying to use argo events + argo workflow . However I am constantly getting this duplicated nodename for ideally not sure why is it saying so . I have a sensor which reacts to events and it has a dag workflow.

apiVersion: argoproj.io/v1alpha1
kind: Sensor

Above is the sensor code for it .

apiVersion: argoproj.io/v1alpha1

spec:
  serviceAccountName: workflow
  templates:
    - name: build-kaniko-git
      inputs:
        parameters:
          - name: repo_url
          - name: repo_ref
            value: refs/heads/master
          - name: repo_commit_id
            value: HEAD
          - name: container_image
          - name: container_tag
      container:
        image: gcr.io/kaniko-project/executor:debug
        command: [/kaniko/executor]
        args:
          - --context={{inputs.parameters.repo_url}}#{{inputs.parameters.repo_ref}}#{{inputs.parameters.repo_commit_id}}
          - --destination={{inputs.parameters.container_image}}:{{inputs.parameters.container_tag}}
        volumeMounts:
          - name: regcred
            mountPath: /kaniko/.docker/

Above is the templateref for the argo workflow for kaniko . The error I keep getting is -
