Hey, I was wondering on how to deal/set more complex parameter structures in Prefect Orion. E.g. when I have lists ore nested models, I can’t set them on the UI at all.

Building this via

prefect deployment build ./param_example.py:example_flow -n example_flow -o example_flow-deployment.yaml

And then applying via:

prefect deployment apply 'example_flow-deployment.yaml'

example_flow.py

It seems for lists the UI is buggy, it looks like it’s supposed to be able to select lists, but in the end it only takes a string value

great example to reproduce and I was indeed able to reproduce -- thanks for raising that and I'll open an issue @Marvin open "UI interprets parameters of type list as strings"

for now as a workaround, when you set those on the deployment YAML, it should work

Copy code

parameters: {}

yep, it works setting them in the YAML. I also realized doing this:

Copy code

def example_flow(params: ExampleParams = ExampleParams()):

sets up the default params directly, so also a good workaround for now
