        const streamingMetadata = Pricing.Metadata.Definition().getStream(session);
        await streamingMetadata.open();

        console.log(streamingMetadata.getFieldDescription('DSPLY_NAME'));
        console.log(streamingMetadata.getFieldDescription(3));

        console.log(streamingMetadata.getFieldEnumeration('CURRENCY'));
        console.log(streamingMetadata.getFieldEnumeration(15));

        await streamingMetadata.close();
    } catch (err) {

    } finally {
        session.close();
    }
