#3785 [BUG] Cannot kickoff executions for workflows containing parameter of type `List[Optional[X]]` Issue created by eapolinario Describe the bug The launchform does not allow for parameters of type

List[Optional[X]]

to be specified, regardless of what type

X

is. For example:

import typing
from flytekit import task, workflow


@task
def t():
    pass


@workflow
def wf(ints: typing.List[typing.Optional[int]]):
    t()

Kicking off an execution via flyteconsole's launch form results in: Expected behavior We should be able to kickoff an execution for these workflows/tasks.
