recipe.get_inputs() gets TypeError: 'NoneType' object is not subscriptable

RYoung

import dataiku
from dataiku import recipe

# simply copy the first recipe input dataset
# to the first recipe output dataset, with the schema

ds_input = recipe.get_inputs()[0]
df_input = ds_input.get_dataframe()

when run in jupiter notebook I get the following error

In a Notebook you first need to establish proper context and point to the project/recipe you want to look at:

import dataiku
client_handle = dataiku.api_client()
project_handle = client_handle.get_project('some_project_key')
recipe_handle = project_handle.get_recipe('some_recipe_id')
recipe_settings = recipe_handle.get_settings()
recipe_settings.get_recipe_inputs()

Hi Turribeach,

tested your code and got.

NameError: name 'recipe_settings' is not defined

My bad, I missed a line of code. Updated the code above now.
