Unable to use vectorcode due to KeyError: '_type'

[JuanG970]

Hi all, I installed vectorcode[legacy] and chromadb using a docker container, my platform is Mac. Unfortunately I see the following failure when doing vectorcode ls or anything vectorcode command, is someone familiar with this issue?

ERROR: vectorcode.main : Traceback (most recent call last):

KeyError: '_type'

Hi, the legacy dep group is mostly for numpy and torch, which don't provide packages for old platforms. That means this error is most likely not caused by the legacy group, but rather other part of the code.

Could you verify the chroma version of the Docker container you're running? If it's 1.0.x, please downgrade it to 0.6.3 and see if it solves the problem. VectorCode doesn't work with chromadb 1.0.x yet.

Yes, that was the issue. Thank you. For reference, to run a Docker container with 0.6.3 I did:

docker run -v ./chroma-data:/data -p 8000:8000 chromadb/chroma:0.6.3
