The '@' character is supposed to be a reserved indicator for YAML. Therefore when using it at the beginning of a string (as in this case) we should enclose it in quotes. http://yaml.org/spec/1.2/spec.html#id2774228 Also, since Symfony 2.8 this kind of usage is already marked as deprecated: https://github.com/symfony/symfony/blob/2.8/UPGRADE-2.8.md#yaml |
