metrics property
Metrics is the upstream transactor's metrics block. This server does not populate it, so it is always the empty object — the front reads the key, not its contents.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
Object? metrics;
