When does this happen?
IF When using Meta Llama 2 model (e.g., meta.llama2-13b-chat-v1) via LangChain's Bedrock class, you get 'Malformed input request: 2 schema violations found'.
How others solved it
THEN Modify the Bedrock provider handling for 'meta' to use 'prompt' as the body key instead of 'inputText'. In `_prepare_input_and_invoke`, add a case for 'meta' that sets the body with a 'prompt' key mapping to the user input.
if provider == 'meta':
body = json.dumps({'prompt': prompt})Related patterns
