No error handling around empty messages

[spocksbrain]

I have also run across this error a number of times.

I'm having this same issue repeatedly, trying to tweak the code but my skills are limited. It happens if there is no continuation prompt and/or when the orchestrator goes back to the sub-agent (I think). I can't seem to get past it.

Try adding this error handling to maestro.py:

if not messages or not system_message:
        console.print("[bold red]Error:[/bold red] Messages or system message is empty, cannot proceed with creating the message.")
        return None

try:
    haiku_response = client.messages.create(
        model=SUB_AGENT_MODEL,
        max_tokens=4096,
        messages=messages,
        system=system_message
    )
    if not haiku_response.content:
        raise ValueError("No content in response")
except Exception as e:
    console.print(f"[bold red]Error:[/bold red] Failed to receive a valid response from the sub-agent. {str(e)}")
    return None

You wanna add this code around line 117, where the code is sending the a message to the sub-agent. The code there looks like this:

haiku_response = client.messages.create(
    model=SUB_AGENT_MODEL,
    max_tokens=4096,
    messages=messages,
    system=system_message
)

...and doesn't have any error handling. The code I pasted just adds error handling.

I just started looking at this project so I don't have the full context of what happens when you return None from this function, but for now it stopped the unhandled exception error. Be on the look out for other side effects.

I have this same issue. Causing me to chew through token credits :(
