Trying to implement a Python Script Advanced Sensor but I get (code: PE233) -- (code: PE231)

Here is my code:

if __name__ == "__main__":
    try:
          #Code to generate the dictionary that I will not put in the question otherwise it gets too long
        dictionary = {"Record_letti": temp2[11], "Record_aggiunti": temp2[17], "Record_modificati": temp2[23], "Record_eliminati": temp2[29], "Record_scartati": temp2[35]} }
        #print(dictionary)
        #create a prtg sensor and add the channel data
        sensor = CustomSensorResult(text="This sensor runs a log reader")
        sensor.add_channel(name='Record Letti',unit='Count',value=dictionary["Record_letti"])
        sensor.add_channel(name='Record Aggiunti',unit='Count',value=dictionary["Record_aggiunti"])
        sensor.add_channel(name='Record Modificati',unit='Count',value=dictionary["Record_modificati"])
        sensor.add_channel(name='Record Eliminati',unit='Count',value=dictionary["Record_eliminati"])
        sensor.add_channel(name='Record Scartati',unit='Count',value=dictionary["Record_scartati"])
        #send the sensor data back to the prtg process in json #format
        print(sensor.json_result)
        #create a prtg sensor and add the channel data
        sensor = CustomSensorResult(text="This sensor runs a log reader")
        print(json.dumps(dictionary, indent = 4))
    except Exception as e:
        sensor = CustomSensorResult(text="Python Script execution error")
        sensor.error = "Python Script execution error: " % str(e)
        print(sensor.json_result)

The log says "Script Output (UTF8 Encoding): File "C:\Program Files (x86)\PRTG Network Monitor\custom sensors\python\FiPlanLogReader.py", line 1[CR][LF] {\rtf1\ansi\ansicpg1252\deff0\nouicompat{\fonttbl{\f0\fnil\fcharset0 Calibri;}}[CR][LF] ^[CR][LF]SyntaxError: unexpected character after line continuation character[CR][LF]"
