# `Castle.Error`
[🔗](https://github.com/ausimian/castle/blob/1.0.0/lib/castle/error.ex#L1)

Raised when Castle refuses a command or `:release_handler` returns an error.

The exception gives `bin/castle` a non-zero exit status without stopping the
managed node. Other exceptions, throws and exits propagate unchanged.
