Error message

Failed to send message

What it means

AgentHandleImpl.send caught an error from agentService.sendMessage for this agent id and rethrew as QECoreError. The message could not be delivered (agent terminated, mailbox closed, or service failure); the payload itself is only the vehicle, not the cause.
