使用包含正则表达式的自定义 GQL 标量类型抛出 Apollo GraphQL 错误 .test()

Question

我正在 TypeScript 中创建一个 GraphQL 自定义标量并构建序列化/parseValue/parseLiteral 函数。我希望我的标量将传入值与正则表达式相匹配，但是当我将

if (value.test(yearMonthDayRegex)) {}

作为条件时，我收到 Apollo 运行时错误：

TypeError: value.test is not a function

有没有办法将正则表达式功能合并到这个自定义标量中？还是我错过了关于 TS 中正则表达式的更基本的东西？我的正则表达式看起来像

const yearMonthDayRegex = /^d{4}-(0?[1-9]|1[012])-(0?[1-9]|[12][0-9]|3[01])$/;
