#3711 fix: Raise EmptySchemaTypeError for empty date schema types Pull request opened by edgarrmondragon Summary by Sourcery Raise a specific EmptySchemaTypeError when date-type schemas are empty and add coverage for this behavior. Bug Fixes: • Ensure is_date_or_datetime_type raises EmptySchemaTypeError for empty schema types instead of a generic ValueError. Tests: • Add a unit test verifying that is_date_or_datetime_type raises EmptySchemaTypeError when invoked with an effectively empty date schema. meltano/sdk
