Current Behavior

Trying to create an index on a collection throws and exception:

pymilvus.exceptions.MilvusException: <MilvusException: (code=1, message=invalid index type: IVF_FLAT")>

Expected Behavior

No response

Steps To Reproduce

The following is the definition of the collection:

    def_news_category = 'General'
    # Define the fields of the schema
    news_id = FieldSchema(
        name='news_id',
        dtype=DataType.INT64,
        is_primary=True
    )
    news_category = FieldSchema(
        name='news_category',
        dtype=DataType.VARCHAR,
        max_length=15,
        default_value=def_news_category
    )
    news_snippet_text = FieldSchema(
        name='news_snippet_text',
        dtype=DataType.VARCHAR,
        max_length=256
    )
    news_snippet_vector = FieldSchema(
        name='news_snippet_vector',
        dtype=DataType.FLOAT_VECTOR,
        dim=200
    )
    # Define the collection
    collection_schema = CollectionSchema(
        fields=[news_id, news_category, news_snippet_text, news_snippet_vector],
        description="News Snippet Search",
        enable_dynamic_field=True
    )
    # Create the collection
    collection = Collection(
        name=collection_name,
        schema=collection_schema,
        using=alias
    )

The following is the snippet to create the index:

    field = 'news_snippet_vector'
    index_params = {
        'metric_type': 'L2',
        'index_type': 'IVF_FLAT"',
        'params': {'nlist': 128}
    }
    collection.create_index(field, index_params)

Looking closely at the logs from stdout ... realized a silli mistake 'index_type': 'IVF_FLAT"', ... see the additional double quote ...
This is not an issue anymore ...
