与 RuleType.object() 不兼容

[li-qs]

midway-component/packages/swagger/src/lib/generator.ts

Line 295 in caf84ab

for (const prop of joiSchema.$_terms?.keys) {

当验证对象里有 RuleType.object() 规则时，/swagger-ui/json 会报错：

object null is not iterable (cannot read property Symbol(Symbol.iterator))

debug 看了下是 joiSchema.$_terms?.keys 的值为 null
