带有Discord API的cURL PUT / PATCH请求导致错误400（错误请求）

Question

我正在使用php，oAuth2（来自Discord）和cURL连接到Discord API，在用户授权连接后，他将自动输入具有特定昵称和角色的服务器（行会），但是如果用户已经在服务器上，只需更改昵称并自动添加角色即可。

我在Auth2上取得了成功，因此我正在研究它。他使用identy，guilds.join和email范围返回了我想要的所有内容。但是，在将成员添加到服务器或编辑成员的过程中，它返回错误400（错误请求）。而且我真的不知道它是什么，所以我所看到的似乎没事。

奇怪的是，昨天它只能在匿名浏览器选项卡中运行，但是今天，它甚至可以在我的普通浏览器中运行，但是对于其他用户而言，则不起作用。

说实话，我已经出现了错误400和403，这确实非常令人困惑。

我的完整代码：

任何帮助将不胜感激。非常感谢。
