Prefect Community

Hi everyone — I have a task that returns a python dictionary, now I’m trying to use one of the elements of the dictionary as input for another task, but I’m getting an error.. Here’s a minimal working example:
```import prefect
from prefect import task, Flow, Parameter, unmapped, case
from prefect.tasks.shell import ShellTask

shell_task = ShellTask(stream_output=True)

@task
def get_config():
    return {
        'path': '/root/',
    }

with Flow("test") as flow:
    config = get_config()
    bar = shell_task(command="pwd", helper_script = f"cd {config['path']}")

flow.run()```

Hey <@U020NQGNUJW>, tasks execution is deferred but that dictionary call is done during build time. So there won’t be `config['path']` to pull yet. In this case you need an intermediate task that takes in `config` and pulls out the `path` and returns it.

it worked! I ended up just enclosing a “shell_task.run()” inside another task, and I only pass the full config object to it and deal with that inside the task — I found this cleaner and more consistent with how I do other tasks

You can also do this in the flow: `task(lambda _x_: x['path'])(config)`
