When fetching content using the Contentful REST APIs the select operator allows you to choose which properties you'd like to retrieve from an entity. However, since the introduction of Tags, the API always returns an extra metadata.tags property.

This is an unintentional behavior that increases the response size. We plan to fix this behavior so that when the select operator is present we only return specified properties.

If you're using select operator and rely on the extra metadata.tags in the response, make sure to include metadata.tags property in the select operator value.
