【问题描述】：
我正在为具有类似 /user/{uid}/cart 的路径的端点开发 AWS Cloud Formation 模板。我需要创建与 HTTP 主机的集成。我一直在尝试将 {uid} 映射到集成请求 URL 路径参数中，如下所示：
"x-amazon-apigateway-integration": {
"uri": "http://${stageVariables.httpHost}/user/{uid}/cart",
"contentHandling": "CONVERT_TO_TEXT",
"timeoutInMillis": 29000,
"connectionType": "INTERNET",
"httpMethod": "PUT",
"passthroughBehavior": "WHEN_NO_MATCH",
"type": "HTTP_PROXY",
"requestParameters": {
"integration.request.path.uid" : "method.request.path.uid"
}...
我不断收到此错误，但我不确定自己做错了什么。
Errors found during import: Unable to put integration on 'PUT' for resource at path '/user/{uid}/cart': Invalid mapping expression specified: Validation Result: warnings : [], errors : [Invalid mapping expression parameter specified: method.request.path.uid]
这是完整的模板
