Zigbee error message and erratic behavior

Hello, I have this error message but I don’t understand what it’s about. Also, my Zigbee network is reacting slowly. I lost a relay socket that disappeared from the interface, I have to re-pair it.

Error: Minified React error #185; visit https://react.dev/errors/185 for the full message or use the non-minified dev environment for full errors and additional helpful warnings.

Hello,

I took the liberty of editing your message to make it more readable.

Are these errors on Gladys’ side or Zigbee2MQTT’s side?

Thanks for the reply, it’s a ztomqtt message I’ve never had that before
