Error message
When this error occurs
This error applies to nested nodes (items) and nested properties (entries in a properties array). Unlike top-level fields, which can be empty to indicate inheritance, nested nodes must explicitly declare their configuration.
A nested node or property with none of enabled_stats, stat_options, self, properties, or items is invalid.
This error does not apply to top-level field entries (e.g.,
dataset.fields[user_id]). A top-level field with only a field_name and no other fields is valid — it means “inherit from the namespace scope or defaults.”Example: request that triggers this error
city has only a path — no stat configuration.
How to fix
Add at least one configuration field to the nested node or property:properties array entirely. Unlisted properties receive no stats.
