Each command is "undefined"

Whenever I try to do something with the extension, say right-click on a container and select `attach`, docker always receives "undefined" in the terminal:

Containers:
```
docker stop undefined
Error response from daemon: No such container: undefined
```
```
docker inspect undefined
[]
Error: No such object: undefined
```

Images:
```
docker inspect undefined:undefined
[]
Error: No such object: undefined:undefined
```
```
docker run -it --name obscene_release undefined:undefined
Unable to find image 'undefined:undefined' locally
```
