Serialise msg object coming from Kafka Producer and store in influxdb in Node-Red flow

I have the flow below in node-red, I need the msg object to be stored in influxdb - enter image description here

As you can see in the debug node coming out of the kafka consumer, the payload is being stored in Influxdb as [object Object] and not in a serialised manner with each column separated. If I store the msg object directly into influxdb(without the kafka producer and consumer in-between), then it's stored in db as required.

Is there a way to store the msg object in the influxdb properly with the kafka producer and consumer being part of the flow?

As worked out in the comments, you need to include a JSON node before the Kafka Producer node because it expects a String as input not a JavaScript Object and the JSON node will Serialise the Object to a JSON string.
