Another probably 🤦‍♂️question. Could someone help me understand why the env parameter in my catalog isn't being injected into the catalog from my

locals/parameters.yml

file? catalog:

parsed_documents:  # Just one document for now.
  type: json.JSONDataSet
  filepath: '<s3://mybucket/${env}/myjson.json>

local/parameters.yml file entry:

env: "main"

in kedro ipython trying to load i am getting:

DataSetError: Failed while loading data from data set JSONDataSet(filepath=mybucket/${env}/myjson.json, protocol=s3, save_args={'indent': 2}).
mybucket/${env}/myjson.json

Do you use a

TemplatedConfigLoader

in

settings.py

? And have you given a

global_path

(from memory, not sure it is the real name, you have commented examples in the file)

i am not but i thought in 0.18.7 we don't have to. is that confirmed wrong?

You can indeed use

OmegaConfigLoader

, but I do not think it is on by default in

0.18.*

By default Kedro still uses the

ConfigLoader

which doesn’t support any templating. From

0.19.0

we are planning to make the

OmegaConfigLoader

the default.

^ that's what I thought. So I don't need to do anything for the above to work right?

No you do, because

ConfigLoader

doesn’t support templating

${env}

is templating so you’ll need to specifically use the

TemplatedConfigLoader

to make that work.

Because I am not templating I am passing in parameters.
