422 Error code

[metallicalfa2]

I'm using docker-compose to run local chroma DB. While using from_documents function, the following error occurs

[rohinrohin]

Me too! It fails in the chroma.fromDocuments, getText, ... function and I think it is related to #1311. I tried to work around this but was not able to successfully.

Source code:

Error:

- error Error: [object Response]
    at ChromaClient.getOrCreateCollection 

Any help is appreciated!

What version of ChromaClient are you using?, That's happening because there's a mismatch between the Chroma version used by Langchain and the actual Chroma version. In the latest version of LangChain, the getOrCreateCollection function is being called with only one argument, but Chroma requires three arguments.

name: string,
metadata?: CollectionMetadata,
embeddingFunction?: IEmbeddingFunction

I see the issue I mentioned before was fixed already
#1348

Can you try updating your Chroma package to > 1.4.2 and bumping your LangChainJS version? #1348 should have fixed this.
