Can't export kubeflow pipelines if I use parameters

[MartinKlefas]

Describe the issue
I've downloaded your notebook server image and successfully submitted a number of pipelines based on your examples and the early stages of my work. I'd like to add parameters to my notebooks, but at present have made a very simple test notebook to try to get my first parametric pipeline created.

To Reproduce
I've made a simple python notebook which just prints "hello {person}". I've then followed this guide https://medium.com/codait/build-versatile-pipelines-in-elyra-using-pipeline-parameters-5634f8d5ae8d#:~:text=Parameterizing%20Pipelines%20in%20Elyra,Node%20Properties%20%2C%20all%20shown%20below. to make a kubeflow pipeline of sorts with single node.
I can save it with no parameters, and can export it to YAML. If I add a parameter, I can still export it to YAML. If I add that parameter to the single node, I'm no longer able to export the pipeline to YAML and get the below error from "argo".

The above exception was the direct cause of the following exception:

Expected behavior
exported YAML file

Deployment information
Describe what you've deployed and how:

• Elyra Version: 3.15.0
• Operating system: Description: Ubuntu 20.04.2 LTS
• Installation source:, official container image
• Deployment type: Kubeflow [notebook server]
  Parameters.zip

Pipeline runtime environment

• Kubeflow Pipelines - latest version

attachment
I've attached the notebook and the pipeline file as those are probably what I've done wrong

It's also worth mentioning that saving as a dsl file produces the python file as expected, but when I run that from the command line I get:

where toWhom is my parameter name.
