container_component parameter check issue

[hankug1234]

/kind bug

What steps did you take and what happened:
i use kfp v2.7.0
and i try to compile my pipeline dsl code

this is my container_component function signature

def whisper(audio: dsl.InputPath(Dataset), model: str, language: str, format: str, output_dir: dsl.OutputPath(Dataset)):

when i compile my code i get some error

Traceback (most recent call last):
File "C:\Users\USER\PycharmProjects\pythonProject\kuberflow\main.py", line 9, in
def my_component(
File "C:\Users\USER\PycharmProjects\pythonProject\kuberflow\venv\lib\site-packages\kfp\dsl\container_component_decorator.py", line 53, in container_component
return component_factory.create_container_component_from_func(func)
File "C:\Users\USER\PycharmProjects\pythonProject\kuberflow\venv\lib\site-packages\kfp\dsl\component_factory.py", line 644, in create_container_component_from_func

raise ValueError(
ValueError: param_type is not a parameter type. Cannot get ParameterType name.

when i see this document
https://kubeflow-pipelines.readthedocs.io/en/latest/source/dsl.html#kfp.dsl.container_component

there is a example that

from kfp.dsl import container_component, ContainerSpec, InputPath, OutputPath, Output

@container_component
def my_component(
dataset_path: InputPath(Dataset),
model: Output[Model],
num_epochs: int,
output_parameter: OutputPath(str),
):
return ContainerSpec(
image='gcr.io/my-image',
command=['sh', 'my_component.sh'],
args=[
'--dataset_path', dataset_path,
'--model_path', model.path,
'--output_parameter_path', output_parameter,
]
)

so i understand container_component can use InputPath class

but

follow error log in found some code in
"C:\Users\USER\PycharmProjects\pythonProject\kuberflow\venv\lib\site-packages\kfp\dsl\component_factory.py", line 623,

def make_input_for_parameterized_container_component_function(
name: str, annotation: Union[Type[List[artifact_types.Artifact]],
Type[artifact_types.Artifact]]
) -> Union[placeholders.Placeholder, container_component_artifact_channel
.ContainerComponentArtifactChannel]:

this code check container_component parameter can acceptable

but it only accept
artifact_wrapped_in_Input type,
artifact_wrapped_in_Output type,
OutputPath type
and primitive type

so i think basically inputPath can't accepted in container_component
but official document example talk inputPath class can acceptable

what is correct?
