I have semantic kernel Open AI configuration that uses chromadb.

 // Initialization
 var collectionName = "mydataMemory";
 await chromaClient.CreateCollectionAsync(collectionName, cancellationToken);

 // Save records
 var chromaMemoryStore = new ChromaMemoryStore(chromaClient);
 var memory = new SemanticTextMemory(chromaMemoryStore, textEmbeddingGenerationService);
 await memory.SaveInformationAsync(collectionName, text, id, description, metadata, cancellationToken: cancellationToken);

 `metadata` and `description` are always empty for now.

Locally when I spawn chromadb in this way:

 chroma run --host localhost --port 8000

All works fine, but when I configure it on the docker compose, I see the following error:

Few notes:

1. As I wrote above, the code works locally (without containers)
2. The localhost:8000 chroma endpoint is replaced on http://chroma_server:8000 in the docker myapp env.
3. Creating collection works even on the Docker Compose side, the problematic step is saving data
4. It's a bit strange why the error is 400, given that the request works locally (without containers), I would assume that the sent arguments are valid.

• There is not enough info. Try increasing the Semantic Kernel log level or adding logging to HttpClient to see what the server response. Also, have you tried to run the ChromaDB in Docker and run your app normally? If it works, then I guess the problem is the ChromaDB version compatibility. – Fahmi Noor Fiqri Commented Feb 28 at 1:03
• 1 Thanks @FahmiNoorFiqri. I did this and found a new output {"error":"InvalidArgumentError","message":"cannot unpack non-iterable coroutine object"} that led me to the bug in the docker image: github/chroma-core/chroma/issues/3798. – dododo Commented Mar 1 at 14:40

It does not like your host name, I guess because of underscore.

Try to replace chroma_server to chroma in your docker compose file.

Thanks @Fahmi Noor Fiqri. After configuring additional output, I noticed that actual error is: {"error":"InvalidArgumentError","message":"cannot unpack non-iterable coroutine object"}. After quick googling, I found that it's a bug in chroma image: https://github/chroma-core/chroma/issues/3798. The solution will be in the version 0.6.4, a stable version of it is not available yet. The prerelease version 0.6.4.dev283 solves the issue too
