Why does Qdrant client fail to create a collection when connecting to a Docker instance but works locally with a path?

[anusonawane]

I'm using the RetrieveUserProxyAgent from AutoGen with Qdrant as the vector database.
When initializing the Qdrant client locally via **QdrantClient(path="qdrant_db")**, the collection is created successfully.
However, when connecting to a Qdrant Docker instance using **QdrantClient(url="http://localhost:6333")**,
it throws a 404 Not Found error indicating the collection autogen-docs doesn't exist, despite get_or_create=True in the configuration.

Reproducible Code:

`from autogen import RetrieveUserProxyAgent, AssistantAgent
from qdrant_client import QdrantClient
import chromadb.utils.embedding_functions as embedding_functions

google_ef = embedding_functions.GoogleGenerativeAiEmbeddingFunction(api_key="your-api-key")
client = QdrantClient(url="http://localhost:6333") # Fails with Docker # client = QdrantClient(path="qdrant_db") # Works locally

ragproxyagent = RetrieveUserProxyAgent(
name="ragproxyagent",
retrieve_config={
"task": "code",
"docs_path": "docs.json",
"chunk_token_size": 2000,
"embedding_function": google_ef,
"db_config": {"client": client},
"vector_db": "qdrant",
"get_or_create": True, # Should create collection if missing
"overwrite": False,
},
)

ragproxyagent.initiate_chat(AssistantAgent(name="assistant"), problem="Sample problem")`

Error:
qdrant_client.http.exceptions.UnexpectedResponse: Unexpected Response: 404 (Not Found) Raw response content: b'{"status":{"error":"Not found: Collection autogen-docs doesn\'t exist!"},"time":0.000015598}'

Qdrant Docker command: docker run -p 6333:6333 qdrant/qdrant

Expected Behavior:
The collection autogen-docs should be created automatically when get_or_create=True (as it does with the local path client).
