hello, I'm facing an issue visualizing my pipeline with

kedro viz

. my node runs correctly, and

kedro catalog list

shows the right entries, but

kedro viz

cannot retrieve credentials defined in my hooks.py. did anyone face the same issue?

kedro viz
KeyError: "Unable to find credentials 'adls_creds': check your data catalog and credentials configuration. See <https://kedro.readthedocs.io/en/stable/kedro.io.DataCatalog.html> for an example."

Someone will reply to you shortly. In the meantime, this might help:

would u be able to provide the longer traceback.

sure,

The above exception was the direct cause of the following exception:

yes u r right, it looks for it there! https://docs.kedro.org/en/stable/configuration/credentials.html

any way to use the hooks instead?

from kedro.framework.hooks import hook_impl
from pyspark import SparkConf
from pyspark.sql import SparkSession
from azure.keyvault.secrets import SecretClient
from azure.identity import DefaultAzureCredential

class AzureSecretsHook:
    def __init__(self):
        self.credentials = None

    @hook_impl
    def after_context_created(self, context) -> None:
        credentials = DefaultAzureCredential(exclude_managed_identity_credential=True)
        vault_url = 'xxx'
        client = SecretClient(vault_url=vault_url, credential=credentials)

        secrets = {
            "client_secret": "client-secret",
            "client_id": "client-id",
            "account_name": "storage-account-bld",
            "tenant_id": "tenant-id",
        }
        adls_creds = {
            "adls_creds":{
                cred_name: client.get_secret(secret_name).value
                for cred_name, secret_name in secrets.items()
            }
        }

        context.config_loader["credentials"] = {
            **context.config_loader["credentials"],
            **adls_creds,
        }
        self.credentials = context.config_loader["credentials"]

Yes you can use hooks to register secrets - https://docs.kedro.org/en/stable/hooks/common_use_cases.html#use-hooks-to-load-external-credentials

i think you will still need to have an empty credentials.yml file

i do have an empty credentials.yml file in locals/

@Gauthier Pierard, let me get back to you on this one. it seems like an issue with our CatalogConfigResolver. we will need to investigate this and revert

ok @Rashida Kanchwala, thanks

kedro viz run --include-hooks

^ This should work, the credentials are not found because it’s coming from a hook

thanks Ankita!! 🙂

i confirm. cheers
