i found the Error. For anyone else who has the same problem, it's because of this line:

local payload="{"state":"${temperature}","attributes": {"friendly_name":"${friendly_name}","icon":"${icon}","state_class":"measurement","unit_of_measurement":"°C","device_class":"temperature","unique_id":"${unique_id}"},"device":${device_info}}"

The problem is: "unit_of_measurement":"°C" this must be changed as follows: "unit_of_measurement":"\u00B0C"
I think he can't handle the ° sign
