I found myself with this same problem, the error message definitely needs to be improved to be more descriptive of the real issue.

Same issue here, python 3.9 and also 3.11 + asdf and Ubuntu.

@beejiujitsu [suggested solution](https://github.com/argoproj/argo-workflows/issues/5506#issuecomment-1233275614) works perfectly and is the most efficient and secure from this thread IMO. ```yaml args: - $(WEBHOOK_URL) - '--include' - '--json' - '{"content": "{{inputs.parameters.content_prefix}} {{inputs.parameters.forked_subgraph_name}}: {{inputs.parameters.forked_subgraph_url}}"}' env:...

You can still make it work just by updating the metadata.json file adding "44" to the array, I've done this a lot of times for other extensions and usually works...
