AWS Cloud Formation模板失敗，指定了無效的映射表達式參數

Question

我正在為一個具有/user/{uid}/cart類的路徑的端點開發AWS雲形成模板。 我需要創建一個與HTTP主機的集成。 我一直在嘗試將{uid}映射到集成請求URL路徑參數中，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"
              }...

我一直收到此錯誤，並且不確定自己在做什么錯。

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]

這是完整的模板

問題是parameters的位置。 這些需要在PUT而不是path 。

    "paths": {
        "/user/{uid}/cart": {
            "put": {
              "tags": [
                "users",
                "cart"
              ],
              "parameters": [
              {
                "name": "uid",
                "in": "path",
                "description": "user id",
                "required": true,
                "type": "string",
                "format": "uuid"
              }
            ],...
