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:
```javascript
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 (??):
```javascript
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.
