Issue with custumizing kedro datasets and the Pokemon Tutorial

[rosanajurdi]

Hello all,
I am struggling with creating custumized datasets in kedro. I am working on the pokemon example in the kedro tutorial handbook. I have created the following code but everytime I try to run, I arrive at the following error.
Does anyone know the origin of the error and how I can fix it ?
Thank you in advance !

catalog:

pikachu:
type: pokemon.extras.datasets.image_dataset.ImageDataSet
filepath: data/01_raw/pokemon-images-and-types/images/images/pikachu.png

pokemon:
type: PartitionedDataSet
dataset: pokemon.extras.datasets.image_dataset.ImageDataSet
path: data/01_raw/pokemon-images-and-types/images/images
filename_suffix: ".png"

pipeline:

from kedro.pipeline import Pipeline, pipeline, node
from .nodes import load_pokemon_images

def create_pipeline():
return Pipeline(
[
node(
func=load_pokemon_images,
inputs = ["pokemon"],
outputs = "pokemon_images",
tags="pokemon", # Use the dataset name defined in your catalog
),
]
)

node:

def load_pokemon_images(dataset):
# Load the dataset using your custom ImageDataSet
images = dataset.load()

# Optionally, you can process or manipulate the loaded data here
# For example, if you want to return the number of images loaded:
num_images = len(images)

return images, num_images

pipeline_registery:

def register_pipelines() -> dict[str, Pipeline]:
"""Register the project's pipelines.

Returns:
    A mapping from pipeline names to ``Pipeline`` objects.
"""
pipelines = find_pipelines()
pipelines["__default__"] = sum(pipelines.values())
return pipelines
