Struggling to get the format correct for this:-

**var VehTemp = "msg.payload.climate\_state.outside\_temp" || 99;**

Have tried separators, moustache's and probably grown a beard while trying!

Thanks!

Why are you putting quotes arround `msg.payload.climate_state.outside_temp`? That turns it into a string.

Tried with and without, added them here to make key clear.

Tried msg [payload],[climate\_state],[outside\_temp], commas separating, inverted commas, many other iterations.

This is the first complex-ish function node I’ve tried, I added a lot of debug which helped me understand other errors but I can’t get to the bottom of this one.  
JS is very new to me...

</div>

When you use `msg.payload.climate_state.outside_temp` you are saying "Get me the value of 'outside\_temp' which is in the object 'climate\_state' which is in the object 'payload' that is inside of the msg" or think of it like this  
msg  
==\> payload  
====\> climate\_state  
======\> outside\_temp

Now if you put a debug node on the output of your `inject` nodes, does that property exist?

If you want to see if a property exists you could use  
`if (msg.payload.hasOwnProperty("climate_state")){`  
to see if "climate\_state" exists in msg.payload, then use  
`if (msg.payload.climate_state.hasOwnProperty("outside_temp")){`  
to see if outside\_temp exists in msg.payload.climate\_state

Thanks Paul,

The property path I copied from debug window so I know it exists- you can see it in the sample data when pressing inject button “ vehData Online Query- Outside Temp 20, full online (O/P2)”.

Thanks for the extra debug steps, I’ll try tomorrow after some sleep!

Post up a screenshot of the debug window and also your flow that you have that is not working

Does it exsist in ALL the `inject` nodes????

Sorry, got back up as it's bugging me, I see what's happening now. The whole function is actually working but I have "TypeError: Cannot read property 'outside\_temp' of undefined" for a couple of situations:-

- error messages don't have climate\_state property (bottom inject button)
- an "offline" query doesn't have climate\_state property (top inject button)

I incorrectly assumed the "or" in "var VehTemp= .... || 99" would just set the variable to 99 in those scenarios- but this doesn't happen if the property isn't there at all. I want to set VehTemp to 99 for these conditions as well...

This OR does work on the second inject button where climate\_state=null is correctly set to 99.

I think I need to add some something boolean to check the climate.state property is present first with "varTemp=..." nested within that if true?

Here's the flow again...

Look at my first post where you test ti see if the property exists in the owner object. You need to do two if' to check for both properties.

Thanks @zenofmud, sorry, never sunk in first time.  
The upper level hasownproperty check works fine and should always apply.

Had to also remove semi-colons as they were escaping before msg return...need to study that a bit more and probably improve error checking- after sleep!
