What happened

snowflake.yml

streamlit:
  name: streamlit_core_metrics_prod

snowflake.local.yml

definition_version: 1
streamlit:
  name: streamlit_core_metrics_preview
  additional_source_files:
    - shared_modules/*.py

Console output

TypeError: YAML(['shared_modules/*.py']) not a mapping, cannot use .items()

How to reproduce

Try to override a field from snowflake.yml that contains a list in snowflake.local.yml -- it only seems to work with 1-to-1 mapping fields, rather than 1-to-list fields.
