Symfony Validation error: preg_match(): Compilation failed: range out of order in character class at offset

Question

当我验证从 Symfony 2.x 更新到 Symfony 4.4 的应用程序的操作时，出现以下错误。
我正在验证的功能是输入id“！”进行验证并确认验证工作正常。半角字母数字字符、下划线 (_)、连字符 (-) 和点 (.) 可用于目标区域。
有什么你能想到的吗？
我删除了form.errors，但是没有用。

错误

我更改了正则表达式，它工作正常。
由于php版本升级，正则表达式方法可能已经改变。

pattern: "/^[a-zA-Z0-9-_.]+$/"
