报错：Setting data field "homeworkList" to undefined is invalid.怎么解决
res.result 打印一下，看一下是不是不是对象
wx.cloud.callFunction({
name: "gethomeworklist",
success: res => {
console.log('res.result:', res.result); // Add this line to log res.result
if (res.result && res.result.success) {
this.setData({ homeworkList: res.result.data });
} else {
wx.showToast({
title: "获取作业列表失败",
icon: "none"
});
this.setData({ homeworkList: [] });
}
},
fail: err => {
console.error("调用云函数失败：", err);
this.setData({ homeworkList: [] });
}
});
},
是这样吗，没用啊，还是报错：Setting data field "homeworkList" to undefined is invalid.
