private ObjectNode fetchObject(EntityKey key, TupleContext tupleContext) {
    LightblueEntityMetadataId entityId = LightblueEntityMetadataId.extractEntityInfo(key.getMetadata());
    DataFindRequest request = new DataFindRequest(entityId.entityName, entityId.entityVersion);
    request.where(new ValueQuery("_id", ExpressionOperation.EQUALS, key.getColumnValues()[0].toString()));
    List<Projection> projections = new ArrayList<Projection>(Arrays.asList(projectionsFromColumns(tupleContext.getSelectableColumns())));
    projections.add(new FieldProjection("_id", true, true));
    request.select(projections);
    try {
        LightblueResponse response = provider.getLightblueClient().data(request);
        if (response.hasError()) {
            throw new RuntimeException("Error returned in response: " + response.getText());
        }
