Hassio RPC Shutdown addon... really need some help

I would like a button on my frontend somewhere that would allow me to shut down a pc remotely. This looks like it should work, but I can’t even make it work with a service call.

Error log output:

ERROR (MainThread) [homeassistant.core] Invalid service data for hassio.addon_stdin: extra keys not allowed @ data['computers']. Got [{'alias': 'test-pc', 'address': '192.168.1.117', 'credentials': 'xxxx%yyyy'}]

As I said, would really like to to be a button on the frontend, but can’t make the simple stuff work!

Thanks Matt

I’ve came up to the same problem.
Following this guide I get a

[homeassistant.core] Invalid service data for hassio.addon_stdin: extra keys not allowed @ data['computers']. Got [{'alias': 'test-pc', 'address': '192.168.1.xx', 'credentials': 'usr%pwd'}]`

I’m a little bit confuse how to use it …
