你好 @zhoubo416!很高兴再次看到你在这里。希望你今天过得很好!
这个错误“TypeError: ids is not iterable”通常发生在你试图迭代一个不可迭代的变量,比如null或undefined。在gpt4-pdf-chatbot-langchain仓库的上下文中,这个错误可能由几个原因引起:
-
请求体中的
history
变量可能是null或undefined。当代码试图映射history
来创建pastMessages
时,这将导致错误。你应该在尝试映射它之前添加检查,以确保history
不是null或undefined。 -
chain.invoke
方法可能返回一个不可迭代的值。如果chain.invoke
应该返回一个可迭代的值,但返回的是null或undefined,那么当代码试图等待documentPromise
时,这将导致错误。你应该在chain.invoke
中添加错误处理,以确保它总是返回一个可迭代的值。 -
handleRetrieverEnd
回调可能被一个不可迭代的参数调用。如果documents
应该是一个可迭代的值,但是null或undefined,那么当代码试图用documents
解决documentPromise
时,这将导致错误。你应该在尝试用documents
解决documentPromise
之前添加检查,以确保documents
不是null或undefined。
没有更多关于错误发生在哪一行的具体信息,很难说出确切的问题是什么。然而,根据提供的上下文,这些是一些可能的原因。你可以在这个链接中查看相关的代码:pages/api/chat.ts。
如果你能提供更多关于错误发生的具体位置的信息,我可能能更好地帮助你解决这个问题。
