app.js:31567 Error fetching Excel data: TypeError: Cannot read properties of undefined (reading 'read')

根据你提供的信息，这个错误是在app.js文件的第31567行发生的。错误信息显示无法读取未定义的属性'read'。这可能是因为在该行代码中，尝试对一个未定义的对象进行读取操作。

要解决这个问题，你可以检查以下几点：
1. 确保在使用'read'属性之前，已经正确地定义了相应的对象。
2. 检查是否正确引入了相关的依赖库或模块，以确保所需的方法和属性可用。
3. 检查代码逻辑，确保在使用'read'属性之前已经对其进行了正确的初始化。

如果你能提供更多的代码或错误堆栈信息，我可以给出更具体的建议。

Error fetching PDF data TypeError: Cannot read properties of undefined (reading 'GlobalWorkerOptions')

这个错误通常是由于pdf.js库的加载问题引起的。pdf.js是一个用于在Web上显示PDF文件的JavaScript库。以下是一些可能的解决方法：

1. 确保正确加载了pdf.js库。你可以检查网络面板或控制台输出来查看是否成功加载了该库。

2. 确保正确设置了pdf.js库的路径。你可以检查你的代码中是否正确设置了pdf.js库的路径。

3. 确保你的代码与pdf.js库版本兼容。你可以检查你的代码是否与你使用的pdf.js库版本兼容。

4. 尝试清除浏览器缓存并重新加载页面。有时候浏览器缓存可能会导致pdf.js库加载失败。

以下是一个可能的解决方案：

<script src="path/to/pdf.js"></script>
<script src="path/to/pdf.worker.js"></script>
<script>
  // 设置pdf.js库的路径
  pdfjsLib.GlobalWorkerOptions.workerSrc = 'path/to/pdf.worker.js';
  
  // 加载PDF文件
  var loadingTask = pdfjsLib.getDocument('path/to/document.pdf');
  loadingTask.promise.then(function(pdf) {
    console.log('PDF加载成功');
  }, function(reason) {
    console.error('PDF加载失败：' + reason);
  });
</script>

zk_dept_apply.vue:293 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'query')

The error message "Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'query')" is a JavaScript runtime error that occurs when you're trying to access a property 'query' on an object that is `undefined`. In this context, it's likely referring to a line 293 in the file 'zk_dept_apply.vue', which seems to be part of a Vue.js application.

Here, the code is trying to access the 'query' method or property of a variable, but that variable hasn't been properly initialized or is null at that point in the execution. To fix this issue, you need to check if the variable exists and has a 'query' property before calling it:

1. Make sure you've assigned a valid object to the variable `query` before using it. For example:

let query;
if (/* condition where query should be fetched */) {
  query = await fetchSomeData(); // Replace with your actual data fetching logic
}

2. If `query` is supposed to come from an external source like Vuex store or an API, ensure the data has been fetched successfully before accessing its properties.

3. Handle potential null or undefined cases by using optional chaining (?.) or nullish coalescing operator (??):

const result = query?.query || defaultQuery; // Use ?? for ES6 compatibility

To get more specific help, I would need to see the surrounding code in the 'zk_dept_apply.vue' file on line 293. However, based on the error message alone, these are general suggestions to troubleshoot the issue.
