Pull request overview
This pull request fixes a bug in OpenAIEmbeddingGenerator where missing or null usage data in the OpenAI API response would cause a NullReferenceException. The fix adds a null check before accessing usage properties and includes comprehensive test coverage for both scenarios.
- Added null-safe handling of
embeddings.Usageto prevent crashes when usage data is absent - Added two test cases covering missing and explicitly null usage fields in API responses
