and the class in the vendor is the original one, no patch apply at all

if i use git to apply the patch it work, but does not with composer

why ?

[ibasaw]

if you want to override symfony/validator in this case, you must change the composer like this

"patches": {
    "symfony/symfonyr": {
        "fix symfony validator": "./patches/fix_validator.patch"
    }
},
