Error message

ElectronDataManagerProxy can only be used in Electron renderer process

What it means

OptimizationError thrown by validateMessageOptimizationRequest when request.messages is null, undefined, or a zero-length array. The optimizer needs the surrounding conversation context, so an empty message list is rejected before any LLM call.

Solutions

1. Guard the call: only invoke optimizeMessage when messages.length > 0.
2. Await conversation/message loading before enabling the optimize action.
3. Debounce or disable actions during message-list load states.
4. Catch OptimizationError and inform the user that context messages are required.

Example fix

// before
await promptService.optimizeMessage({ selectedMessageId: id, messages: [], modelKey });

// after
if (!messages.length) throw new Error('Conversation context required');
await promptService.optimizeMessage({ selectedMessageId: id, messages, modelKey });

if (!Array.isArray(request.messages) || request.messages.length === 0) throw new Error('Context messages required');

function hasMessages(r: unknown): r is { messages: unknown[] } {
  return Array.isArray((r as any)?.messages) && (r as any).messages.length > 0;
}

try { await svc.optimizeMessage(req); } catch (e) { if (e instanceof OptimizationError && /Messages array/.test(e.message)) await reloadConversation(); }

When it happens

Trigger: Calling optimizeMessage with messages: [] or omitting the field — e.g. optimizing before conversation history loads, or passing a filtered array that matched nothing.

Common situations: Race where the messages prop hasn't populated, filtering messages by a predicate that returns empty, or state initialized to [] and the action firing on mount.
