I've set up multiple agents and have started separate sessions with each of them in the Web Chat UI. I have intermittent issues where sometimes they'll respond to the prompt, other times their response appears to be to an internal message that I'm not seeing in the logs with openclaw logs --follow (assuming I do not have the correct log level set, it's currently default and I only see basic gateway messages, not prompts or agent interactions). While sometimes the message is different, it's most frequently the following when testing the hello-world skill from the docs:
Tool call
{
"action": "send",
"message": "Greetings! How may I assist you today?",
"target": "openclaw-control-ui"
}
Tool output
{
"status": "error",
"tool": "message",
"error": "Channel is required (no configured channels detected)."
}
I only use the Web Chat UI, I do not have channels configured at all since they are all third-party. I do not see a way to configure web chat or internal memory as a channel in the docs.
