Got Errors with my configuration of Openmqttgateway

Hello I’m using a fan with a 433mhz remote control. So I want to use a esp32 with cc1101 and openmqttgateway. So far so easy, cause that works. But with my configuration in HA I’m always get this error:

Can someone help me to prevent this error?
