AttributeError: 'str' object has no attribute 'items'
Any help on why its hitting

What is the catalog looking like?
t
an example,
Copy code
_data_source.int_pq: &int_pq
  type: spark.SparkDataSet
  layer: int
  file_format: parquet
  save_args:
    mode: overwrite


data_source.int_detail:
  <<: *int_pq
  filepath: ${base_path_spark}/detail

data_source.int_summary:
  <<: *int_pq
  filepath: ${base_path_spark}/summary
n
you probably forget to use
_
somewhere in the catalog
t
but there are a lot of them
n
a
Yep, the interpolation keys should begin with
_
in the catalog
t
aah ok ok got it
thanks both or the quick reply
n
Actually - I am not sure if it works with YAML anchor (
<<
)if you are using OmegaConf, worth double checking because the preferred way to do so with OmegaConf is using interpolation.
t
Thanks for the help, the solution worked really well. and anchoring is working as well 🙂

Thanks for reporting! I didn't know that it works too!
