Search for Snowflake table column entities returning no results

[klan315]

Hi, Using your code in migratePurview I was able to search for and export all of my Snowflake tables and views. However, when I execute the following to search of Snowflake table columns it returns no results. There is no error message, just no results.

mytypes = 'snowflake_table_column' filter_setup = {'typeName': mytypes} results = client.discovery.search_entities(query='*', search_filter=filter_setup)

Why does it return no results? My Purview map has over 25,000 snowflake table columns.

Thank you
