 * Collection path: What is the path of the collection that you would like to export? You may use `{wildcard}` notation to match a subcollection of all documents in a collection (for example: `chatrooms/{chatid}/posts`). Parent Firestore Document IDs from `{wildcards}`  can be returned in `path_params` as a JSON formatted string.
 
+* Enable logging failed exports: If enabled, the extension will log event exports that failed to enqueue to Cloud Logging, to mitigate data loss.
+
 * Enable Wildcard Column field with Parent Firestore Document IDs: If enabled, creates a column containing a JSON object of all wildcard ids from a documents path.
 
 * Dataset ID: What ID would you like to use for your BigQuery dataset? This extension will create the dataset, if it doesn't already exist.
