handleMessage 中的错误：RangeError：超出最大调用堆栈大小

Question

我在我的 firebase 函数项目中使用“kotlinx-serialization-runtime-js”。到目前为止，一切都按预期进行。但由于我正在使用：

val js = kotlinx.serialization.json.Json(JsonConfiguration.Stable)
             .kotlinx.serialization.stringify(result)

我无法在函数模拟器中本地运行它。启动时会显示在日志中：

Error in handleMessage: {"frb":{"cwd":"/home/drindt/.../functions","projectId":"c*******r-d*********t","triggerId":"","emulators":{},"socketPath":"/tmp/fire_emu_144610.sock"},"opts":{"nodeBinary":"/usr/bin/node","env":{"GOOGLE_APPLICATION_CREDENTIALS":"/home/drindt/.config/firebase/credentials.json"}}} => RangeError: Maximum call stack size exceeded: RangeError: Maximum call stack size exceeded
at extractTriggers (/home/drindt/.npm-packages/lib/node_modules/firebase-tools/lib/extractTriggers.js:2:32)

extractTriggers 的递归调用会导致问题。我在另一个文件中发现，当这个错误发生时，是因为导出了其他模块，而不仅仅是功能模块。我查看了 kotlin 编译的 js 文件确认了这一点。如果我从上面删除 stringify 一切正常。 如果我能得到一些帮助来解决这个问题，那就太好了。感谢您花时间阅读并帮助我。

我在这里遇到了同样的问题，由于我还不能发表评论（没有足够的声誉），我将我的问题发布在这里，它的解决方案是：

简而言之，对我的教训是

不要在index.ts 中将export const 用于除函数之外的任何内容。

所以对我来说它显示以下错误：

functions: Maximum call stack size exceeded
function was killed because it raised an unhandled error.

当我查看firebase-debug.log 文件时，我发现错误源自extractTriggers.js，它位于：

/Users/$name$/.cache/firebase/tools/lib/node_modules/firebase-tools/lib/extractTriggers.js

但我仍然无法弄清楚根本原因是什么，所以我使用console.log 打印出在extractTriggers.js 中调用的函数名称：

i  firestore: Firestore Emulator logging to firestore-debug.log
i  ui: Emulator UI logging to ui-debug.log
i  functions: Watching "/Users/****/Desktop/.../firebase-cloud-functions/functions" for Cloud Functions...

仔细看，发现重复是在函数名firebaseAdmin之后开始的。 我已经在 index.ts

中导出了 firebase 管理实例

import * as admin from 'firebase-admin';

//...

export const firebaseAdmin = admin;

这是这一切的根本原因，只是删除该行，并在所有其他文件中使用单独的导入对我有用！
