Unable to create a workflow template using http request

[ashokdonepudi]

I am using Http POST method to create a argo workflow template , but i am getting invalid character response . I could not able to find proper documentation related to it . Can you please help me in how to create workflow template via HTTP request call . I tried content-type as both JSON and YAML .

Note: If I am using the same template data via argo cli I could able to create it successfully.

POST URL : https://localhost:2746/api/v1/workflow-templates/argo

Template data :

apiVersion: argoproj.io/v1alpha1
kind: WorkflowTemplate
metadata:
  name: workflow-template-whalesay-template
spec:
  entrypoint: whalesay-template
  templates:
    - name: whalesay-template
      inputs:
        parameters:
          - name: message
      container:
        image: docker/whalesay
        command:
          - cowsay
        args:
          - "{{inputs.parameters.message}}"

You're getting a 400 error per the screenshot. invalid character 'a' refers to the first character in your YAML file (the 'a' in apiVersion).

I tried content-type as both JSON and YAML .

I'm not sure if YAML Content-Type is supported. You can use JSON, but you must convert the file to a JSON file. The first character in JSON is an opening brace {.

You also have your Body set to binary in Postman, but I think you want raw.

Note: If I am using the same template data via argo cli I could able to create it successfully.

If you turn on debug logging, the CLI will print out the request it's making to the API.
