Failed to evaluate deployment data

[paullotz]

Hello,
I am trying to deploy to two different nodes. Node melon works flawlessly with executing deploy .#melon. "raspberry" is a Raspberry Pi 4 which I am using with remote build set to true so this shouldnt be an issue. When executing deploy .#raspberry I get an error that I cannot resolve:

Any help is appreciated. thank you :)

Found the issue..
nixosConfigurations paraenthesis was not enclosing raspberry.

Note, I have just received a Raspberry pi 3 as a gift from a friend. There will be a configuration committed soon.
