Unable to start the bundled chromadb

[blankenshipz]

I recently have gotten into a state where the chromadb doesn't seem to start, any ideas what I might be doing wrong? Here's a debug log from vectorcode ls

INFO:vectorcode.main:Shutting down the bundled Chromadb instance.

[Davidyz]

This appears to be a bug introduced by 0.6.8. I'll fix this soon. Sorry about that.

This bug should only affect the bundled chroma server. If you set up a standalone chroma server (via docker or systemd, etc.), you should be able to use it just fine.

[Davidyz]

Fixed on main and will be part of the next release.

Thanks!
