   Here is an example, I have to check if they are empty before adding them to a batchwrite, if the array is empty it will error. I want it to ignore empty arrays would remove my need to do this check.

   try {
           let questionStoreInstance = questionStore.batchWrite();
           if (questionsToDelete.length !== 0) {
               questionStoreInstance = questionStoreInstance.delete(questionsToDelete);
           }
   
           if ((questionsToCreate.length + questionsToUpdate.length) !== 0) {
               questionStoreInstance = questionStoreInstance.put([...questionsToCreate, ...questionsToUpdate])
           }
   
           await questionStoreInstance.exec();
       } catch (e) {
           logger.error(`Cannot update questions: ${e}`);
           return buildReturnBody(e);
       }
