[Fix] Error when using FlyteFile as default value in workflow

[machichima]

Tracking issue

Why are the changes needed?

When running local workflow with the default args value set as FlyteFile, we will get following error:

What changes were proposed in this pull request?

1. In FileParamType's convert function, if the value is already FlyteFile, directly return value to prevent creating the nested FlyteFile

How was this patch tested?

Test by running script:

DEFAULT_LOCAL_PATH = "./test.txt"

@task
def my_task(dataset: FlyteFile):
    print(f"path: {dataset.path}")

@workflow
def wf(file: FlyteFile = FlyteFile(DEFAULT_LOCAL_PATH)):
    outputs = my_task(dataset=file)

Summary by Bito

This pull request fixes a bug in handling default `FlyteFile` values in workflows by modifying the `convert` function in the `FileParamType` class. It ensures that existing `FlyteFile` instances are returned directly without nesting, allowing local workflows to execute smoothly with `FlyteFile` as a default argument.

Do we also need to update DirParamType for FlyteDirectory?

[machichima]

Sure! I'll open a follow-up PR for updating DirParamType

It seems like FlyteDirectory will not have this issue 🤔
Following works

def my_task(dataset: FlyteDirectory):
    print(f"path: {dataset.path}")


@workflow
def wf(dir: FlyteDirectory = FlyteDirectory(DEFAULT_LOCAL_DIR)):
    outputs = my_task(dataset=dir)
