Klipper sometimes doesn't connect to mcu error:-32601

Describe your issue:

I have a super racer klipperized, it works all perfectly via usb, but when i connect raspberry pi 3a+ to the mcu via uart, klipper stuck to “status:startup” on mainsail and “unknown” on fluidd, i’ve noticed an error in moonraker.log(code:-32601) but i don’t know what it mean. I have always to restart the printer 2 o 3 times to make it work. I want to connect it via uart to put raspberry inside the case of the printer.

From the log it seems that even the USB connection is unstable.
