There is no proper serialization for Header and Cookie non-trivial (NOT 'isPrimitiveType') parameters, like AnyValue, QMap<QString, T> (which is free-form object), QList<AnyValue>, etc

Since 3.0 (and still in 3.1.1) parameter serialization rules were updated and improved. Now non-trivial types can be used as Path, Query, Header, Cookie parameter.

See: https://spec.openapis.org/oas/v3.1.1.html#style-values

Actual result:

Compilation error at follwoing line:

QJsonObject parameter = paramName.asJsonObject();

Expected result:

Each ^isPrimitiveType parameter is transformed to the QString according serialization tables here:
