…M auth LiteLLMSDKEmbeddings unconditionally required an API key and always passed it to litellm, which broke AWS Bedrock models that use IAM credentials (e.g. ECS task role). litellm interprets the api_key kwarg as aws_access_key_id, overriding ambient IAM auth. Now api_key is optional and only forwarded when set, matching the pattern already used by the LLM provider in litellm_llm.py. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
