optionalOldSelf

optionalOldSelf is used to opt a transition rule into evaluation even when the object is first created, or if the old object is missing the value. When enabled oldSelf will be a CEL optional whose value will be None if there is no old value, or when the object is initially created. You may check for presence of oldSelf using oldSelf.hasValue() and unwrap it after checking using oldSelf.value(). Check the CEL documentation for Optional types for more information: https://pkg.go.dev/github.com/google/cel-go/cel#OptionalTypes May not be set unless oldSelf is used in rule.
