Hi all.

Very new to Node Red.

I have an MQTT node, with this output:

`Preformatted text`{"topic":"flow-meter/heartbeat7","payload":"+112","qos":0,"retain":false,"\_msgid":"rf6226f9.aug622"}

I want to use a change node to remove the text ""flow-meter/" from the object.

There is no JSONata option available. (please see image)

 ![Node Red](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/5/8/589b8bbd7edc0ae1057ca098ab7f3bb0d4119598.png)

I would be grateful if anyone could let me know how to do this.

"flow-meter/heartbeat7" appears to be in msg.topic, not in msg.payload and certainly not in global.payload.

Try Delete msg.topic in the change node.
