LUIS异常：操作返回了无效的状态码“禁止”

Question

遇到这样的错误。之前只是某个时间。 现在，即使是简单的“嗨”，它也给了我这个例外。

请帮助。

即使最初的问题没有遵循mcve，使用LUIS时也存在两个与403相关的常见陷阱。

创作/订阅密钥错误或没有

使用LUIS处理来自网络的样本时，必须提供LUIS应用程序的订阅和创作密钥。在最新的机器人生成器示例中，它通常位于*.bot文件中，如图here所示。

official documentation中描述了编写键和查询的概念。

403超出通话量配额

您已达到LUIS启动键的配额限制。为了永久解决此问题，请遵循我的指导here。
