Description

While executing a request, using @codebase context provider, an error occurrs: Error: lance error: LanceError(IO): k must be positive. I tried reindexing the files via "Click to reindex", also tried deleting the .continue/index, but it didn't help.

The error occurs both with default all-MiniLM-L6-v2 embedding provider and with ollama nomic-embed-text.

The same error occurs in Rider (Rider 2024.2.7, continue 0.0.75)

To reproduce

1. Open Continue chat
2. Enter the request with @codebase context provider, e.g. "what are application entry points? @codebase"

Expected Result: Prompt with some codebase is sent to LLM

Actual Result: The error occurs:
Error getting context items from codebase: Error: lance error: LanceError(IO): k must be positive, C:\Users\runneradmin.cargo\registry\src\index.crates.io-6f17d22bba15001f\lance-0.10.18\src\dataset\scanner.rs:432:27

Log output

The workaround is to set params for codebase context provider:

  "contextProviders": [
    {
      "name": "codebase",
      "params": {
        "nRetrieve": 25,
        "nFinal": 5,
        "useReranking": false
      }
    }
  ],
