In the below argo workflow specification

• I am generating a list of booleans from generate-booleans step.
• I want to conditionally execute step1 if the 0th element of the list is true.

I have tried many combinations of the expression in the when but I am unable to get a condition that executes the step1 if 0th element is true. Either the condition is not satisfied or there is an issue with token with a hint of add quotes around "$" or "{{".

        when: "\"{{=jsonpath(tasks.generate-booleans.outputs.parameters.boolean-list \"$[0]\")}}\" == \"true\""

        import json
        with open('/tmp/output.txt', 'w') as f:
          json.dump([True, False], f)
    outputs:
      parameters:
      - name: boolean-list
        valueFrom:
          path: /tmp/output.txt

  
  - name: task-a
    container:
      image: alpine
      command: [sh, -c, "echo 'Task A executed'"]

Could you please let me know the correct syntax? ps: I have tried fromJson, sprig expressions but failed.
