Steps to replicate behavior

from hamilton import driver
from hamilton.function_modifiers import does
from hamilton.ad_hoc_utils import create_temporary_module


def _identity(**kwargs) -> int:
    return 1

@does(_identity)
def foo(bar: int=1) -> int:
    pass

h_dr = driver.Driver({}, create_temporary_module(foo))
h_dr.raw_execute(['foo'])

python ./demo-hamilton-bug.py
Traceback (most recent call last):
  File "/Users/elijahbenizzy/dev/hamilton-os/sf_nlp/etls/./demo-hamilton-bug.py", line 14, in <module>
    h_dr.raw_execute(['foo'])
  File "/Users/elijahbenizzy/dev/hamilton-os/hamilton/hamilton/driver.py", line 147, in raw_execute
    self.validate_inputs(user_nodes, inputs)  # TODO -- validate within the function graph itself
  File "/Users/elijahbenizzy/dev/hamilton-os/hamilton/hamilton/driver.py", line 102, in validate_inputs
    raise ValueError(error_str)
ValueError: 1 errors encountered:
  Error: Required input bar not provided for nodes: ['foo'].

Library & System Information

E.g. python version, hamilton library version, linux, etc.
