Firebase可调用函数调用时持续返回401未认证错误，请求排查方向

我是个编程新手，11月底才开始用AI帮自己做一个React Web应用，现在正尝试部署到生产环境。但调用Firebase可调用函数时一直碰到401未认证错误，折腾好久了，想问问大家有没有新的排查方向😭

错误信息 #

Failed to load resource: the server responded with a status of 401 ()
LGChat.js:78 Full error object: FirebaseError: The function must be called while authenticated.

问题现状 #

明明我已经完全登录了，Firebase Storage能正常拉取当前账号关联的文档，说明认证功能本身没坏——我甚至删除重建过账号，确认auth流程没问题。而且根据我对可调用函数的理解，Firebase会自动处理token的生成和传递，我代码里没做过影响token的操作，但每次调用函数时，Firebase自己生成的token发过去后还是被拒绝了，实在想不通token会有问题。

已完成的排查步骤 #

LLM们大多建议检查环境配置，我把它们提到的每一项都核对过了，也确认自己完全登录了Google Cloud SDK。具体做过的排查包括：

• 仔细检查了所有可能的环境配置问题
• 确认已登录Google Cloud
• 对照可调用函数官方文档确认配置正确
• 核对过gcloud密钥等信息，确保无误
• 确认其他Firebase服务（比如Storage）能正常工作
• 给所有用户都设置了函数调用者权限
• 每次重新部署前都会清缓存

相关代码片段 #

错误是从我的functions/index.js和LGChat.js文件里抛出来的，下面是相关代码：

LGChat.js 中的函数调用代码

const processDocument = async () => {
  if (!selectedFile || isProcessing || isProcessed || !currentUser) return;

  setIsProcessing(true);
  setError(null);
  setProcessingStatus('Starting processing...');

  try {
    // Use the already initialized functions instance from above
    const processPdfDocument = httpsCallable(functions, 'processPdfDocument', {
      timeout: 540000
    });

    console.log('Processing document with auth:', {
      uid: currentUser?.uid,
      email: currentUser?.email
    });

    console.log('Document details being sent:', {
      fileId: selectedFile.id,
      fileName: selectedFile.name,
      fileUrl: selectedFile.url,
      userId: currentUser.uid
    });

    setProcessingStatus('Processing PDF...');
    console.log('Processing PDF...');
    const result = await processPdfDocument({
      fileId: selectedFile.id,
      fileName: selectedFile.name,
      fileUrl: selectedFile.url,
      userId: currentUser.uid
    });
    console.log('Processing PDF result:', result);

    if (result.data?.success) {
      setIsProcessed(true);
      setProcessingStatus(
        `Successfully processed ${result.data.pagesProcessed} pages`
      );
    } else {
      throw new Error(
        'Processing failed: ' + (result.data?.error || 'Unknown error')
      );
    }
  } catch (error) {
    console.error('Error processing document:', error);
    setError(error.message || 'Failed to process document.');
    setIsProcessed(false);
    setProcessingStatus('Processing failed');
  }
};

functions/index.js 中的可调用函数代码

我实在没辙了，有没有大佬能给指个新方向？因为是新手，麻烦尽量讲得直白些，我可能听不懂太专业的术语😭 如果需要我提供更多信息，也请随时说！
