Whats wrong here with getting enviroment variables?

[haegar33]

Just updated to V3.1 and now, for the first time, wanna try to use global enviroment variables. But I am already stucked with this first example. Output is nil or undefined
An enviroment variable NAME has been defined via the new editor.

Hi @haegar33

In your Inject node, the property should be NAME not ${NAME}

As you have set the field type as 'env var', if you use ${NAME} then the runtime will first substitute the value of ${NAME} with the value of the NAME env var... which is then used as the name of the env var to lookup for the field...
