From the information provided, are you trying to connect milvus with langchain-milvus? Did you try using vanilla milvus pymilvus sdk?

hi, @magallardo Is your pymilvus version == v2.0.0rc2 ? maybe it is a little bit old for langchain_milvus. and after you upgrade your pymilvus version, can you try this code snippet

from pymilvus import MilvusClient
URI = "http://76.208.102.187:19530" # your uri
milvus_client = MilvusClient(uri=URI)

then try your langchain milvus code

vector_store_loaded = Milvus(
    embeddings,
    connection_args={"uri": URI},
    collection_name="langchain_example",
)
