No sources

Error message

No sources

What it means

Thrown by `GlobalConfig::rag_sources` in src/config/mod.rs:1426 when a RAG session IS active but `rag.get_last_sources()` returns `None` — meaning no retrieval has produced citation sources yet (e.g. no query has been answered through the RAG since it was loaded). It is distinct from the 'No RAG' branch in the same function, which fires when no RAG is loaded at all.

Solutions

1. Run at least one RAG-backed query first, then request the sources
2. If the query legitimately matched nothing, treat 'no sources' as an expected empty state rather than an error
3. Check `rag.get_last_sources().is_some()` before calling and fall back to a friendly message

Example fix

// before
let sources = Config::rag_sources(&config)?;
// after
match config.read().rag.as_ref().and_then(|r| r.get_last_sources()) {
    Some(s) => println!("{s}"),
    None => println!("No sources yet — run a RAG query first"),
}

let has_sources = config.read().rag.as_ref()
    .and_then(|r| r.get_last_sources()).is_some();
if !has_sources {
    eprintln!("No sources yet — run a RAG-backed query first");
}

match Config::rag_sources(&config) {
    Ok(s) => println!("{s}"),
    Err(e) if e.to_string() == "No sources" => println!("(no sources recorded yet)"),
    Err(e) => return Err(e.into()),
}

When it happens

Trigger: Calling `Config::rag_sources(config)` right after entering RAG mode, before any chat/query has run through the RAG; after a query that retrieved nothing; after the sources cache was cleared on a fresh `Rag::load`.

Common situations: Users asking for '.last sources' (or equivalent) immediately after loading a RAG; scripts that fetch sources before the first RAG-backed answer; queries whose embedding matched no documents.

Understand the failure class

Background: EmptyResultError / "no results found": when an API or scraper succeeds but returns zero rows — this error's family across 9 libraries.
