2026-05-12 14:48:47,167|[WARNING]|1533|140324328559360|dlt|validate.py|verify_normalized_table:113|In schema `facebook_graph_rest_api_source`: The following columns in table 'page_insight_values' did not receive any data during this load and therefore could not have their types inferred:
  - post_attachment_types_csv
  - post_created_time
  - post_id
  - post_status_type
  - value_boolean
  - value_json

Unless type hints are provided, these columns will not be materialized in the destination.
One way to provide type hints is to use the 'columns' argument in the '@dlt.resource' decorator.  For example:

@dlt.resource(columns={'post_attachment_types_csv': {'data_type': 'text'}})
