argo workflow submit error - duplicated node name

[defyjoy]

I am working on argo and trying to learn but I am not finding what is the issue in this code to cause the error below --

And the ClusterWorkflowTemplate for build -

apiVersion: argoproj.io/v1alpha1
kind: ClusterWorkflowTemplate
metadata:
  name: container-image
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/

But what I receive error on webhook trigger is this -

What am I doing wrong here ?

[gitarns]

@defyjoy . Try to remove the parameters for the tasks you don't have, at the end of the file.

[ltartarini]

Got the same issue, any news?

[tomaszwostal]

@gitarns I can confirm. If you delete unused parameters, workflow is successfully submitted.

[defyjoy]

@gitarns This did solve the issue but for some reason I am not able to get any parameter from the body at all

What do you see if you use argo cli to submit the same workflow?
