为Amazon ApiGateway中的URI指定了无效的HTTP端点

我正在尝试使用cloudformation模板使用API​​网关的GET方法创建资源/ user / devices，但它给了我以下错误

发生错误：ApiGatewayRootMethod-为URI指定了无效的HTTP端点（服务：AmazonApiGateway；状态代码：400；错误代码：BadRequestException；请求ID：xxxxxxxxxx）

下面是我的cloudformation模板，

您为Type: "HTTP"指定了ApiGatewayRootMethod，但HTTP接受了API端点URL。您指定的URI格式由Type: "AWS"获取。

从AWS文档：

用于集成的统一资源标识符（URI）。

如果为Type属性指定HTTP，请指定API端点URL。

如果为Type属性指定MOCK，请不要指定此属性。

如果为Type属性指定AWS，请指定遵循以下形式的AWS服务：arn：aws：apigateway：region：subdomain.service | service：path | action / service_api。例如，Lambda函数URI遵循以下格式：arn：aws：apigateway：region：lambda：path / path。该路径通常采用/ 2015-03-31 / functions / LambdaFunctionARN / invocations的形式。有关更多信息，请参阅Amazon API Gateway REST API参考中的集成资源的uri属性。

如果您为Type属性指定HTTP或AWS，则必须指定此属性。
