Hi, I am experiencing a catastrophic error with A0. I keep getting an error 'A0: Message misformat, no valid tool request found.' When I try to fix the error, it disconnects and I get a new error message ' backend disconnected and Token 'B' and ' bad gateway' JSON not valid. Then the entire A0 UI stops working. I restart my Docker container, but the error still persists. Can anyone help, please?
