According documentation

Mark a List<String> or List<Object> field as being represented as the component data selector.

when using the following kind of code

 @Option
 @Documentation("Schema.")
 @Structure(type = Structure.Type.OUT, discoverSchema = GUESS_SCHEMA)
 private List<SchemaInfo> schema = Collections.emptyList();

We expect, to fill an Object matching all or a set of properties matching the Schema.Entry interface...
But, in fact in javascript code, it cannot handle anything but only the entry name (of Schema.Entry class):

parent[key] = body.entries.map(entry => entry.name);
