1 month ago Hello @bguzela! I'm here to help you with any bugs, questions, or contributions you have regarding Dify. Let's tackle this issue together while we wait for a human maintainer.
The error “[anthropic] Error: Messages.create() got an unexpected keyword argument 'headers'” occurs because the Messages.create() method in the Anthropic SDK does not accept a headers argument, but it is being passed one.
To resolve this issue, you need to ensure that the headers argument is not being passed to the Messages.create() method. Here is the updated function:
def _generate_anthropic(self, model: str, credentials: dict, prompt_messages: list[PromptMessage], model_parameters: dict,
stop: Optional[list[str]] = None, stream: bool = True, user: Optional[str] = None) -> Union[LLMResult, Generator]:
"""
Invoke Anthropic large language model
:param model: model name
:param credentials: model credentials
:param prompt_messages: prompt messages
:param model_parameters: model parameters
:param stop: stop words
:param stream: is stream response
:return: full response or stream response chunk generator result
"""
client = AnthropicBedrock(
aws_access_key=credentials.get("aws_access_key_id"),
aws_secret_key=credentials.get("aws_secret_access_key"),
aws_region=credentials["aws_region"],
)
extra_model_kwargs = {}
if stop:
extra_model_kwargs['stop_sequences'] = stop
system, prompt_message_dicts = self._convert_claude_prompt_messages(prompt_messages)
if system:
extra_model_kwargs['system'] = system
response = client.messages.create(
model=model,
messages=prompt_message_dicts,
stream=stream,
**model_parameters,
**extra_model_kwargs
)
if stream:
return self._handle_claude_stream_response(model, credentials, response, prompt_messages)
return self._handle_claude_response(model, credentials, response, prompt_messages)By ensuring that the headers argument is not included in the call to client.messages.create(), the function will now work without raising the error [1][2].

Steps to reproduce
All my agents that were running with the anthropic API (Claude Sonnet and Claude Haiku), now show the following error: “[anthropic] Error: Messages.create() got an unexpected keyword argument 'headers'”. All of them, that once were perfectly working, now show this error, does not matter what I write in the prompt.
✔️ Expected Behavior
I was just expecting the agents to work as they were before.
❌ Actual Behavior
The agents with anthropic’s LLM are not working.
