chapter 1 -> Create a Parquet-based Table in Athena

SELECT *
FROM dsoaws.amazon_reviews_tsv
WHERE product_category = 'Digital_Video_Download' LIMIT 10

should be
SELECT *
FROM dsoaws.amazon_reviews_parquet
WHERE product_category = 'Digital_Video_Download' LIMIT 10

Note from the Author or Editor:
Good catch. Needs to be updated to reflect the correct table `FROM dsoaws.amazon_reviews_parquet`. Thanks.

data_bias_config

When I set group_name = "product_categeory" for the clarify.BiasConfig as set in the book and accompaying notebook, I get a ClientError on this:

"ClientError: facet name_or_index:'product_category' cannot be the same as group_variable. Please specify a facet other than group_variable. group_variable: product_category
"

What is the correct solution? Thanks in advance.
