Pull Request Overview
Adds validation of embedder configurations before indexing to prevent misleading "file watcher started" messages and ensure clear error reporting.
- Introduce
validateConfiguration()inIEmbedderand implement it for all embedder types. - Integrate validation in
CodeIndexServiceFactoryandCodeIndexManager, halting indexing on invalid config. - Expand i18n localization keys for validation errors and update webview handler to catch and rethrow validation failures.

- The validation method returns the key
embeddings:validation.invalidResponse, but this key isn’t defined in the locale files. Please add aninvalidResponseentry undervalidationin allembeddings.jsonlocale files.
error: "embeddings:validation.invalidResponse",
src/services/code-index/embedders/openai.ts:207
- The code uses the translation key
embeddings:openai.invalidResponseFormat, but there’s no corresponding entry in the i18n locale files. Please add this key or adjust to an existing key so the message is localized correctly.
error: t("embeddings:openai.invalidResponseFormat"),
src/i18n/locales/en/embeddings.json:14
- The Ollama embedder code references
embeddings:errors.ollama.serviceNotRunning, but this key is declared directly underembeddingsrather than nested undererrors.ollama. Please align the key path in the locale file with the code reference.
"serviceNotRunning": "Ollama service is not running at {{baseUrl}}",

I was testing it by setting an invalid API key for the OpenAI provider, and it seems like the new settings aren't being saved. Instead of showing an error for the invalid key, the system appears to continue using my previous (valid) key. From what I can tell, the Ideally, the settings should be saved first, and then any errors should be shown during service initialization. That way, the user gets clear feedback about what’s wrong without losing their changes. |

- Added missing ollama.title, description, and settings keys - Fixed translation check failure in CI/CD pipeline - Synchronized all 17 non-English locale files
- Validate embedder connection when switching providers - Prevent misleading 'Indexed' status when embedder is unavailable - Show immediate error feedback for invalid configurations - Add comprehensive test coverage for validation flow This ensures users get immediate feedback when configuring embedders, preventing confusion when providers like Ollama are not accessible.

Typographical note: The new string uses "embedder" instead of the transliterated "эмбеддера" as used in the previous key ("Неверная конфигурация эмбеддера."). For consistency, consider using "эмбеддера" here as well.

- Restored codebaseIndexSearchMaxResults and codebaseIndexSearchMinScore settings that were unintentionally removed - Keep embedder validation related changes
- Reverted point ID generation back to using line numbers instead of segmentHash
- Restored { cause: deleteError } parameter in scanner error handling
- These changes were unrelated to the embedder validation feature

Description
Fixes #4398 - Code indexing was showing misleading status indicators when embedder configurations were invalid. Users would see both "standby" state and a green "file watcher started" message, suggesting the system was working when it was actually failing silently due to invalid embedder settings.
Closes: 5350
This PR adds proper validation during embedder instantiation to ensure configurations are valid before starting the indexing process. Users now receive immediate, actionable feedback about configuration issues.
Changes Made
Core Implementation
validateConfiguration()method toIEmbedderinterfaceCodeIndexServiceFactoryto validate embedder before returning instanceCodeIndexManagerto validate embedder before proceeding with indexingwebviewMessageHandlerReview Feedback Addressed
Based on PR review feedback, the following improvements were made:
i18n Consistency in Ollama Embedder
Timeout Handling with AbortController
Better Error Message Preservation
Testing
Test Coverage
Quality Checks
Translations
No new translations were required. All embedder validation error messages use existing translation keys in
src/i18n/locales/*/embeddings.jsonfiles that were already present and translated in all supported locales.Verification of Acceptance Criteria
✅ Invalid embedder configurations immediately show error state
✅ No "file watcher started" message appears for invalid configurations
✅ Clear, actionable error messages help users fix configuration
✅ System recovers gracefully when configuration is corrected
✅ All embedder types have appropriate validation
Checklist
Important
Adds embedder configuration validation to prevent misleading status indicators and improve error handling in the code indexing process.
