TypeError: Workflow.run_workflow()

General
1

I am trying to run the CacheWorkflow example (What are Workflows? - Agno).

However, when I call the .run() method, I get the following error:
TypeError: Workflow.run_workflow() takes 1 positional argument but 2 were given

This is the code I am using

class CacheWorkflow(Workflow):
    # Purely descriptive, not used by the workflow
    description: str = "A workflow that caches previous outputs"

    # Add agents or teams as attributes on the workflow
    agent = Agent(model=model)

    # Write the logic in the `run()` method
    def run(self, message: str) -> Iterator[RunResponse]:
        logger.info(f"Checking cache for '{message}'")
        # Check if the output is already cached
        if self.session_state.get(message):
            logger.info(f"Cache hit for '{message}'")
            yield RunResponse(run_id=self.run_id, content=self.session_state.get(message))
            return

        logger.info(f"Cache miss for '{message}'")
        # Run the agent and yield the response
        yield from self.agent.run(message, stream=True)

        # Cache the output after response is yielded
        self.session_state[message] = self.agent.run_response.content


foo = CacheWorkflow()
response = foo.run("What time is it?")

This is the error message:

---------------------------------------------------------------------------

I am using version 1.5.10. I have also updated to the current version 1.6.2 and get the same error.

Hey @foo_bar
thanks for reaching out and supporting Agno. I’ve shared this with the team, we’re working through all requests one by one and will get back to you soon.
If it’s urgent, please let us know. We appreciate your patience!

Hi @foo_bar
You will have to pass the message like this , since run function take message as input
response = foo.run(message="What time is it?")
Its working for me when i do it like the above.
