PHP-CS-Fixer: Error while using binary_operator_spaces

Each time I want set align_double_arrow or align_equals to true in my .php_cs, I got an error:

Loaded config default from "/var/www/project/.php_cs".
E
Legend: ?-unknown, I-invalid file syntax, file ignored, S-Skipped, .-no changes, F-fixed, E-error

Fixed all files in 0.013 seconds, 6.000 MB memory used

Files that were not fixed due to errors reported during fixing:
   1) /var/www/project/CSTestController.php

With this file https://gist.github.com/AntoineLemaire/d8153d17fca3b1e67ef2dc98810180b3

And this .php_cs

<?php

return PhpCsFixer\Config::create()
    ->setUsingCache(false)
    ->setRules(array(
        '@Symfony' => true,
        'array_syntax' => array('syntax' => 'short'),
        'unalign_equals' => false,
        'phpdoc_order' => true,
        'phpdoc_to_comment' => false,
        'binary_operator_spaces' => array(
            'align_double_arrow' => true,
            'align_equals' => true,
        ),
    ))
;

I’m using php 7.0.13
