failed to get embedding model: %w

Error message

failed to get embedding model: %w

What it means

Thrown when modelService.GetEmbeddingModel fails to resolve the embedding model configured on the knowledge base (kb.EmbeddingModelID) during summary-chunk indexing. The summary cannot be embedded into the vector store without it.

Solutions

1. Verify the KB's embedding model ID exists, is enabled, and matches the vector store dimension
2. Check model provider credentials
3. Retry summary indexing after fixing configuration
