Function correctCancelError

coderd/rbac/error.go:121–127

correctCancelError will return the correct error for a canceled context. This is because rego changes a canceled context to a topdown.CancelErr. This error is not helpful if the code is "canceled". To make the error conform with the rest of our canceled errors, we will convert the error to a context

(err error)

// error. No good information is lost, as the topdown.CancelErr provides the
// location of the query that was canceled, which does not matter.
func correctCancelError(err error) error {
	e := new(topdown.Error)
	if xerrors.As(err, &e) || e.Code == topdown.CancelErr {
		return context.Canceled
	}
	return err
}
