Hello! Maybe this is a known thing, but does the Flyte UI not support inputs of

List[Type]

where the

Type

is complex? Or maybe I’m just specifying my input incorrectly: I specifically have a workflow with an input

List[FlyteFile]

that is passing that input to task that takes a

List[FlyteFile]

. When I try to run this workflow through the Flyte UI, passing an input like

["test_file.txt"]

and the workflow starts running, the UI shows that this was my input:

Copy code

{
  "test_list": [
    "(empty)"
  ]
}

So as you can imagine, the workflow then fails to run:

Copy code

Message:

    Cannot convert from scalar {
  none_type {
  }
}
 to <class 'flytekit.types.file.file.FlyteFile'>

SYSTEM ERROR! Contact platform administrators.

I gave this a test in the sandbox to make sure the same thing happened there too, I just modified the

hello_world

one slightly:

Copy code

@task
def say_hello(test_list: List[FlyteFile]) -> str:
    return "hello world

@workflow
def my_wf(test_list: List[FlyteFile]) -> str:
    res = say_hello(test_list=test_list)
    return res

And then registered:

Copy code

pyflyte -c ~/.flyte/config-sandbox.yaml register --version ref2 core/flyte_basics/hello_world.py

And this was my result

UI might not support that, FlyteFile has a specific input format i think. You can submit it from FlyteRemote right

Ah gotcha, that makes sense. Yeah I can give that a test, I have a workflow calling this one as a subworkflow that I tested with too, and it was able to run successfully, so it definitely seems like a UI thing from that

Could you try to pass below value as input on the Flyte Console

Copy code

[{
  "dimensionality": 0,
  "uri": "<s3://bucket/test_file.txt>"
}]

"dimensionality": 0

means it’s a blob file

@glamorous-carpet-83516 do we have this documented somewhere? Specifically the input strings for different types in the UI? I think it could be very useful.

We don’t have doc now, but we should add it. However, you could see the correct format on the console when you specify default input for the workflow. After you register a workflow that has default input, you’ll see the default format on the UI when launching the workflow.
