No endpoints configured

Error message

No endpoints configured

What it means

UpdateError::NoEndpointsConfigured is returned before any network I/O when the custom updater's endpoint list is empty. It renders exactly 'No endpoints configured' and indicates a configuration problem, not a runtime/network problem.

Solutions

1. Verify the updater endpoints configuration exists and is non-empty before calling update_check
2. Check the config file/key that supplies the endpoint list actually loads
3. Ship sensible default endpoints as fallback in the code
4. Guard the UI so the update check is disabled when no endpoints are configured

Example fix

// before
let endpoints = load_endpoints()?;
// after
let endpoints = load_endpoints()?;
if endpoints.is_empty() {
    eprintln!("updater: no endpoints configured, skipping check");
    return Ok(None); // or use a default list
}

const endpoints = loadEndpoints();
if (!endpoints || endpoints.length === 0) {
  throw new Error('updater misconfigured: no endpoints; fix settings before checking for updates');
}

function hasEndpoints(cfg: UpdaterConfig | null): cfg is UpdaterConfig & { endpoints: string[] } {
  return !!cfg && Array.isArray(cfg.endpoints) && cfg.endpoints.length > 0;
}

When it happens

Trigger: update_check is invoked while the configured endpoints array is empty or was never loaded (missing config file, config key absent, or empty array from settings).

Common situations: Fresh install without a bundled updater config; user wiped settings; environment-specific config not deployed; a bug clearing the endpoints list after saving preferences.
