Assuming the env value always exactly matches the property names in the payload, you can use

```auto
const prop = env.get('sensor')
indata = RED.util.getObjectProperty(msg.payload,prop);
...

```

PS: About your post formatting:

In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote `````)

````auto
``` 
   code goes here 
```

````
