Error message

creating safesearch for client %q: %w

What it means

Creating the safe-search configuration for a client failed while converting JSON to a client object. The wrapped error comes from the safe-search engine when the client's SafeSearchConf is invalid or the cache settings are unusable.

Solutions

1. Check the wrapped error for the specific safe-search setting at fault
2. Simplify the request: omit safe-search fields, then re-add them one at a time
3. Verify global safe-search cache size/TTL configuration is sane
4. Upgrade both client tooling and server to matching versions

// Omit or null safe_search fields when unsure
if !validatedSafeSearch(payload.SafeSearchConf) { payload.SafeSearchConf = nil }

// Degrade gracefully: resend without safe-search settings
if isSafeSearchErr(err) { payload.SafeSearchConf = nil; retry() }

When it happens

Trigger: handleAddClient/handleUpdateClient (or internal consistency assertions) with a client whose SafeSearchConf fails to build into a safe-search set, e.g. invalid engine options or bad cache size/TTL values.

Common situations: API payloads with malformed safe-search settings, inconsistent global safe-search cache configuration, or version mismatches where the config schema changed.
