问题代码：

live2d-widget/src/index.js

Line 134 in ae27493

modelId = 1; // 模型 ID

本项目默认加载modelId为1的模型。
当使用cdn方式加载模型时，modelId将作为数组下标。

live2d-widget/src/model.js

Line 32 in ae27493

const target = randomSelection(this.modelList.models[modelId]);

而当cdn中只有一个模型时，this.modelList.models 这个数组将只存在一个元素，即下标为0的那个元素
而默认modelId默认为1，故this.modelList.models[1]将返回undefined。
这最终导致target这个原本应该是模型名称的变量成为undefined。

我目前的做法是修改 waifu-tips.js 中的这个函数，把它们的值都改成 0

然后模型就可以正常加载了（可能我选择的模型比 live2d_api 默认模型大，导致 <canvas /> 画不全）

谢谢反馈，已修复： cc487fa
后端API默认会给模型id增加1，导致API与CDN模型id不一致
