报错 <Lambda, this> is not a sequence

什么情况下面这段脚本会报错 ` is not a sequence`？本地运行没有问题，但是提交到 Hive 在 UDF 中运行就会抛这个异常，百思不得其解😕

刚开始以为是有一个名为 `dts` 的匿名函数类型的全局环境变量，所以在执行时出错了，但本身是用单独实例来执行的脚本，应该不存在全局环境变量污染的问题，另外无论是给 `dts` 改名还是把 `cnt` 写成一个 `Function` 而不是一个 `Lambda` 后仍然报错，就很奇怪。

**脚本：**
```lua
let recall_days = 30;
let order_rate = 0.7;
let behave_rate = 0.3;
let date_bound = Dates.format(Dates.sub(Dates.from(now()), recall_days, Dates.DAY), 'yyyyMMdd'); ## Dates 是一个 Java 工具类
let cnt = fn(dts) { count(filter(dts, lambda(dt) -> dt >= date_bound end)) };
let score = fn(mp) { cnt(mp.order) * order_rate + cnt(mp.behavior) * behave_rate };
into(seq.map(), map(interacts, lambda(etr) -> seq.entry(etr.key, double(score(etr.value))) end))
```

**脚本传参结构：** `interacts`：`Map>>`，eg. `{"1": {"order": ["20241110"], "behave": ["20241109"\]}}`

**脚本目的：** 根据用户的订单和行为情况（互动天数）来计算其偏好得分

**Aviator 版本：** 5.4.3

Start with RuntimeUtils.java and SeqFilterFunction.java at the stack-trace entries, then reproduce the supplied script and input in both local execution and the Hive UDF context. Compare the value passed to filter in each environment; done means identifying why a Lambda is treated as a non-sequence and documenting or correcting the version-specific behavior in Aviator 5.4.3.
