What it means

Solutions

1. Ensure the save form validates name before calling the IPC
2. Pass preset.name as a non-empty trimmed string
3. Add a required-field check in the UI so users can't submit blank names

Example fix

// before
await ipcRenderer.invoke('config:save-preset', { name: '', config })

// after
const name = nameInput.trim()
if (!name) throw new Error('Preset name is required')
await ipcRenderer.invoke('config:save-preset', { name, config })

const isValidPreset = (p: { name?: unknown }) =>
  typeof p?.name === 'string' && p.name.trim().length > 0

const hasValidPresetName = (p: unknown): p is { name: string } =>
  typeof (p as any)?.name === 'string' && (p as any).name.trim() !== ''

try { await ipcRenderer.invoke('config:save-preset', preset) } catch (e) { showFieldError('name', (e as Error).message) }

When it happens

Trigger: Renderer sends config:save-preset with preset.name = '', whitespace-only, undefined, or a non-string value (e.g. number).

Common situations: Form state where the name input was never filled, or a refactor that renamed the field (label vs name).
