Regarding: https://symfony.com/doc/current/validation/translations.html
From: #19054 (comment)

From my experience in a project where I tried to use it like that it failed as the type declaration only allows "string" (https://github.com/symfony/validator/blob/6.4/Context/ExecutionContext.php#L157C21-L157C35) or so I miss something here?

Even TranslateableMessage implements "__toString" does not help as it would only return the template-message without resolving/translating it. (https://github.com/symfony/translation/blob/6.4/TranslatableMessage.php#L35)

I checked it for the version I used (6.4) but it seems to be the same for 7.X - if I missed something maybe we can clarify the example 🙏🏻
