节点红色用 [error] [function:check for lost changes] xx ERRORS 淹没系统日志

Question

我有一个节点红色流，在工作时系统日志中充斥着这样的消息：

Jul 10 06:31:07 NodeRedPi Node-RED[12267]: 10 Jul 06:31:07 - [error] [function:check for lost changes] 35 ERRORS

Jul 10 06:31:22 NodeRedPi Node-RED[12267]: 10 Jul 06:31:22 - [error] [function:check for lost changes] 27 ERRORS

这可能是什么原因？

有趣的是，如果流程停止工作，消息将不再出现。

Answer 1

这是一个由名称为 check for lost changes 的函数节点记录的错误。

在该节点内将包含一些代码，其中包含记录此消息的 node.error(...) 语句。

您问这个问题表明您不是自己编写 Function 节点。

打开流编辑器，找到该节点（Ctrl-F 搜索名称 'check for lost changes'）并打开其编辑对话框。这将向您显示它包含的代码。从那里，您将必须弄清楚代码在做什么以及导致它记录此错误的原因。
