Hey all, I am just trying to run a flow from the UI that works just fine when kicked off from python... I am just using the "Get Github Stars" flow/task from the docs, and wanted to pass in params from the UI. It is not going as expected. When I am trying to pass them in from the UI, I get each character passed to the task instead of each individual string in the parameters. See screenshots in thread. Is this just a formatting issue with the parameters?

Hi @Adam Brusselback - can you try adding a type to your parameter so the UI knows what type you are trying to enter? I find the list here at pydantic useful: https://pydantic-docs.helpmanual.io/usage/types/

I did try that, no dice on getting it working though.

import httpx
from prefect import flow, task


@task(retries=3)
def get_stars(repo: str):
    url = f"<https://api.github.com/repos/{repo}>"
    count = httpx.get(url).json()["stargazers_count"]
    print(f"{repo} has {count} stars!")


@flow()
def github_stars(repos: list):
    for repo in repos:
        get_stars.submit(repo)


# call the flow!
if __name__ == "__main__":
    github_stars(["PrefectHQ/Prefect", "PrefectHQ/prefect-aws", "PrefectHQ/prefect-dbt"])

Looks like it’s a 🐛. There’s an open issue on the topic that you can track here. Please add a comment if it’s an important use case for you.

It's somewhat important, was planning on having somewhat rich parameter lists built out for my tasks, and the ability to pass in lists of values is one of the requirements

Thanks @Adam Brusselback - apologies that I didn't recognize the bug. The team are actively working on this one!
