Heyo, not sure how to get the correct formatting from the node-red-contrib-tesla to node-red-node-geofence.

Here's the output of the node-red-contrib-tesla driveState command:

```auto
{"_msgid":"15f2c9c.3bb0a36","payload":{"gps_as_of":1620781503,"heading":94,"latitude":xxxx,"longitude":-xxxx,"native_latitude":xxxx,"native_location_supported":1,"native_longitude":-xxxx,"native_type":"wgs","power":0,"shift_state":null,"speed":null,"timestamp":1620781574744},"topic":""}

```

I believe the payload.latitude & payload.longitude need to be msg.location.lat & msg.location.lon so I put the below into a change rule but that doesn't seem to have done anything.

Here's the output of the change rule:

```auto
{"_msgid":"15f2c9c.3bb0a36","payload":{"gps_as_of":1620781503,"heading":94,"latitude":xxxx,"longitude":-xxxx,"native_latitude":xxxx,"native_location_supported":1,"native_longitude":-xxxx,"native_type":"wgs","power":0,"shift_state":null,"speed":null,"timestamp":1620781574744},"topic":""}

```

I'm quite new to using Node-RED and not good with any type of JSON so was hoping someone here could help.

Thanks!

You have the arguments wrong way round in the change node.  
you should read it as set msg.something to _the value of_ something.

You might also need to set `msg.location` to JSON `{}` first (first row of change node) to initialise the location as an object before setting the lat & lon.

Or change the set to move
