Getting undefined error in flow.get

[GravityRZ]

Hello,

i work with flow.get and global.get a lot
however i get an error in the currrent flow but do not see anything wrong

de output is undefined but it should state up (the value of network.192.168.1.25.ipstate

i suspect that the ipaddress having dots is causing the problem but how to solve this

flow including function

Here you are:

status = flow.get('network')[msg.topic]["ipstate"];

The problem comes because you are trying to use 192.168.1.25 as part of the key name.

The full key you function code generates is

'network.'+msg.topic+'.ipstate'

which results in:

'network.192.168.1.25.ipstate'

It doesn't recognise 192.168.1.25 as a single key name, rather it interprets that as the four distinct object property levels.

The fix is to either generate a key like:

'network["192.168.1.25"].ipstate'

using:

'network["'+msg.topic+'"].ipstate'

or as @techraf suggests, get the whole network object first and then pull out the bits you need.

thanks, almost tried everything (including using ) but sometimes i just can not get it right.
