How to use the stream-json/streamers/StreamObject.streamObject function in stream-json

export function parseDocumentIncludes(
    bodyStream: stream.Stream,
    conventions: DocumentConventions) {
    return RavenCommandResponsePipeline.create<{ [key: string]: object }>()
        .parseJsonAsync([
            pick({ filter: "Includes" }),
            streamObject()
        ])
        .streamKeyCaseTransform(conventions.entityFieldNameConvention, "DOCUMENT_LOAD")
        .collectResult((result, next) => {
            result[next["key"]] = next["value"];
            return result;
        }, {})
        .process(bodyStream);
}
