bug: document upload is broken on version 0.5.8

[louis-jan]

Jan version

0.5.8

Describe the Bug

When uploading document, I don't see any request was made on /embeddings endpoint. After that, the app stuck at generating response.

After investigation, the root cause is that the Assistant Extension is outdated with the latest Cortex endpoints. There was a configuration that routed to an old Nitro instance.

See timeWeightedVectorStore configs which are hard coded

Steps to Reproduce

1. Start a new chat
2. Upload a pdf document
3. See the error

Screenshots / Logs

Proposed solution

• Update configs to match the latest cortex-server instance.

Future enhancement

• Run a fixed embedding models such as Nomic by default to serve /embeddings endpoint.
• The selected GUI model is for chat operations only.

Can upload now, though the responses were rubbish, but that's another separate issue.
