Failed to update setting: {err}

Error message

Failed to update setting: {err}

What it means

Wrapper produced by normalize_reasoning_effort_setting when ReasoningEffort::parse_strict rejects the trimmed value: after the sentinel words (default/config/unset) are excluded, the remaining string is not a recognized effort level. The {err} carries the parser's specific complaint; the setting update aborts with no change.

Solutions

1. Use a supported reasoning-effort value as accepted by ReasoningEffort (e.g. minimal/low/medium/high per the current parser)
2. Use 'default' or 'unset' to clear the override instead of an unknown word
3. Check the inner {err} text for the exact accepted vocabulary
