为什么节点脚本从命令运行，但在从cronjob调度时会出现错误？

Question

我在macos，并计划一个节点脚本作为一个cronjob。我正在将cron作业的日志保存到一个文件中。当脚本使用我在cronjob中的相同命令从shell手动执行时，它成功地执行，但是它会从cronjob中产生错误。

该脚本使用snoowrap请求从reddit获取顶级帖子。我想这就是错误的来源。错误是：

RangeError: Maximum call stack size exceeded

    at processImmediate (node:internal/timers:466:21)
node:internal/process/promises:265
            triggerUncaughtException(err, true /* fromPromise */);

我在crontab中使用的命令是

~/Documents/learns/myproj/job.sh >> ~/Documents/learns/myproj/cron.log 2>&1，job.sh有

~/.nvm/versions/node/v16.14.0/bin/node ~/Documents/learns/myproj/build/index

这是代码中产生错误的部分。

await this.redditClient
        .getSubreddit(subreddit)
        .getTop({ time: "day", limit: 400, count: 400 });

我也尝试过传递--max-stack-size 32000，但仍然给出了相同的错误。

原因是什么，我该如何解决？

说出来很难不看你的代码。我最好的猜测是，在没有等待前一个函数完成的情况下，您触发了太多的函数。尝试使您的代码同步运行，甚至更好地查看Call async/await functions in parallel
