send to InfluxDBv2 sink connector with Python Producer

Hi,

i have problems to send a message with a python producer which should be 
processed by an InfluxDBv2 sink connector.

With a java test code it is possible. 

Java class:

`
 public class Device  {
        public String measurement;
        public long timestamp;
        public Map<String, String> tags;
        public Map<String, Object> fields;
   }`

Set values:
`Device device = new Device();
        
   device.measurement = "test5";
   device.timestamp = Instant.now().toEpochMilli();
   device.tags = Maps.newHashMap();
   device.tags.put("foo", "bar");
   device.fields = Maps.newHashMap();
   device.fields.put("temp", 14.8);`

Device device = new Device();
        
   device.measurement = "test5";
   device.timestamp = Instant.now().toEpochMilli();
   device.tags = Maps.newHashMap();
   device.tags.put("foo", "bar");
   device.fields = Maps.newHashMap();
   device.fields.put("temp", 14.8);

Create producer:

   Producer<Device> producer = client.newProducer(JSONSchema.of(Device.class))
                                                    
.topic("persistent://public/default/foobar")
                                                    .producerName("test")
                                                    .create();

Send message:

   MessageId msgID = producer.newMessage()
                    .key("test")
                    .value(device)
                    .send();

Any suggestions how to do with Python ?

Thanks
