修改下这个写法，捕获异常 const dataSources = computed(() => { const a = chatStore.getChatByUuid(+uuid) // if (a.length > 20) // a.splice(0, a.length - 20) return a.map((item, index) => ({ ...item, key: `${item.dateTime}-${index}`, })) })

```javascript const dataSources = computed(() => { try { const a = chatStore.getChatByUuid(+uuid); if (a.length > 20) { a.splice(0, a.length - 20); } return a.map((item, index) => ({ ...item, key: `${item.dateTime}-${index}`, })); } catch (error) { console.error("Error in computing dataSources:", error); return []; // Return an empty array in case of an error } }); ```
