🎨 Centralize error throwing for encryption keys and credentials (#3105)

* Centralized error throwing for encryption key

* Unifying the error message used by cli and core packages

* Improvements to error messages to make it more DRY

* Removed unnecessary throw

* Throwing error when credential does not exist to simplify node behavior (#3112)
