最新的main分支应该已经修复当前问题。
不过，自定义接口处不能直接填写官方的地址（可使用/api/google做转发）。因为官方地址不支持跨域。

The latest main branch should have the current issue fixed.
However, the official address cannot be directly filled in at the custom interface (/api/google can be used for forwarding). Because the official address does not support cross-domain.
