fetch presets: %w

Error message

fetch presets: %w

What it means

The provider presets cache fetcher tried all configured preset sources and every one failed. Because there was no previously cached result (`c.data == nil`), it cannot fall back to stale data and instead returns a wrapped aggregate error via `fmt.Errorf("fetch presets: %w", err)`. It signals that provider preset data (e.g. model/provider lists shown in the UI) is completely unavailable, not just stale.

Solutions

1. Verify network connectivity to the presets source URL (curl the URL configured as the presets source).
2. Fix the presets source URL in config.toml if it is wrong or unreachable.
3. Configure a local/alternative presets source URL that is reachable from the host.
4. If offline operation is expected, accept degraded behavior or pre-populate the cache by running once with network access.

Example fix

// before
data, err := cache.Fetch(ctx)
if err != nil { return err }

// after
data, err := cache.Fetch(ctx)
if err != nil {
    slog.Warn("provider presets unavailable, using built-in defaults", "error", err)
    data = defaultPresets
}

u, err := url.Parse(presetsSourceURL)
if err != nil || u.Host == "" { return fmt.Errorf("bad presets source %q", presetsSourceURL) }
// optionally: ping the URL once at startup before relying on it

data, err := cache.Fetch(ctx)
if err != nil {
    slog.Warn("presets unavailable, using defaults", "error", err)
    data = defaultPresets
}

When it happens

Trigger: Calling the exported fetch path on the presets cache when (a) every source URL failed to fetch (network down, DNS failure, non-200 responses) AND (b) no successful fetch ever happened before, so `c.data` is nil.

Common situations: Running cc-connect offline or behind a corporate proxy that blocks the presets URL; misconfigured presets source URL in config; DNS resolution failure on a fresh install before the first successful fetch populated the cache.
