智谱API密钥配置不成功

我已经在config文件里配置我的API密钥，如下：

运行时返回如下错误：

将同样的API密钥输入到输入区后却可以正常使用：

Start by reading the config file and the runtime error shown in the attached screenshots, then compare configuration loading with the input-area path that works with the same API key. Done means a key configured in the file works at runtime without entering it manually.
