That row also specifies a value for the subscribersLost metric, but it does not specify values for other metrics.

The list below identifies the API's core metrics.Р”Р„ny of these metrics that are also used in the YouTube Analytics API are also core metrics in that API. In the definitions on this page, any metric that is a core metric is explicitly identified as such. While the YouTube Reporting API is subject to the Deprecation Policy defined in the Terms of Service, non-core metrics (and non-core dimensions) are not subject to the policy. User activity metrics include things like video view counts and ratings (likes and dislikes). Metrics are individual measurements of user activity, ad performance, or estimated revenue. This API retrieves bulk data reports that contain YouTube Analytics data for a channel or content owner. This document defines the metrics that the YouTube Reporting API retrieves.
