Building a RAG application using Spring AI 1.0.0.M1 version, Ollama & Milvus 2.3.0 vector store running as a docker container

Application is able to insert the document; however when I execute below statement for the retrieval

List documents = vectorStore.similaritySearch(SearchRequest.defaults()
.query(question.question()).withTopK(5));

key name when I debug is ‘distance’

I get following exception,

io.milvus.exception.ParamException: The key name is not found

Created a new Collection in the default Milvus vector store as shown below,

ConnectConfig connectConfig = ConnectConfig.builder()
.uri(CLUSTER_ENDPOINT)
.build();

    MilvusClientV2 client = new MilvusClientV2(connectConfig);

    CreateCollectionReq.CollectionSchema schema = client.createSchema();

    schema.addField(AddFieldReq.builder()
            .fieldName("embedding")
            .dataType(DataType.FloatVector)
            .dimension(1024)
            .description("vector embedding")
            .build());

    schema.addField(AddFieldReq.builder()
            .fieldName("id")
            .dataType(DataType.Int64)
            .isPrimaryKey(true)
            .autoID(true)
            .build());


    CreateCollectionReq quickSetupReq = CreateCollectionReq.builder()
            .collectionName(collection_name)
            .collectionSchema(schema)
            .dimension(1024)
            .vectorFieldName("embedding")
            .metricType("COSINE")
            .enableDynamicField(true)
            .build();

    client.createCollection(quickSetupReq);

    IndexParam indexParamForVectorField = IndexParam.builder()
            .fieldName("embedding")
            .indexName("vector_index")
            .indexType(IndexParam.IndexType.IVF_FLAT)
            .metricType(IndexParam.MetricType.COSINE)
            .extraParams(Map.of("nlist", 1, "nprobe", 1))
            .build();

    List<IndexParam> indexParams = new ArrayList<>();
    indexParams.add(indexParamForVectorField);

    CreateIndexReq createIndexReq = CreateIndexReq.builder()
            .collectionName(collection_name)
            .indexParams(indexParams)
            .build();

    client.createIndex(createIndexReq);

Tried different parameters to create the Collection; however still get the same exception, where key name is distance. I have not created any distance field,
