Hello @zyu, thank you for reporting the error. I was not able to reproduce it with version 0.3.22. Could you provide more details about the code and the context in which the error occurs? Did you try update to the last version of chroma?

Thanks

@zyu, In the trace I see references to opentelemetry. We've added OTEL only in version 0.4.x. Can you please double check your Chroma version - pip list | grep chromadb. Thank you.

[tazarov]

@zyu, the issue affects 0.4.x and is being worked on. We'll have a PR for it soon.
