Function ValidateRoute

routing/datasource.go:500–529

ValidateRoute processes a route definition through all configured preprocessors and validates that all resulting routes can be successfully processed. This function is specifically designed for validation webhooks where: - Preprocessors may add additional routes (like OAuth callback routes) - All r

(o *Options, def *eskip.Route)

//
// Returns an error if any preprocessor fails or any resulting route is invalid.
func ValidateRoute(o *Options, def *eskip.Route) error {

	for _, preprocessor := range o.PreProcessors {
		mdef = preprocessor.Do(mdef)
		if len(mdef) == 0 {
			return fmt.Errorf("preprocessing route failed while validating")
		}
	}

	mp := mapPredicates(o.Predicates)
