Question

我正在尝试使用aws-amplify API（base on documentation）添加一个针对Elasticsearch域的自定义地理位置搜索解析器

我的自定义堆栈json是：

{
    "AWSTemplateFormatVersion": "2010-09-09",
    "Description": "An auto-generated nested stack.",
    "Metadata": {},
    "Parameters": {
        "AppSyncApiId": {
            "Type": "String",
            "Description": "The id of the AppSync API associated with this project."
        },
        "AppSyncApiName": {
            "Type": "String",
            "Description": "The name of the AppSync API",
            "Default": "AppSyncSimpleTransform"
        },
        "env": {
            "Type": "String",
            "Description": "The environment name. e.g. Dev, Test, or Production",
            "Default": "NONE"
        },
        "S3DeploymentBucket": {
            "Type": "String",
            "Description": "The S3 bucket containing all deployment assets for the project."
        },
        "S3DeploymentRootKey": {
            "Type": "String",
            "Description": "An S3 key relative to the S3DeploymentBucket that points to the root\nof the deployment directory."
        }
    },
    "Resources": {
        "QueryNearbyUsers": {
            "Type": "AWS::AppSync::Resolver",
            "Properties": {
                "ApiId": {
                    "Ref": "AppSyncApiId"
                },
                "DataSourceName": "ElasticsearchDomain",
                "TypeName": "Query",
                "FieldName": "nearbyUsers",
                "RequestMappingTemplateS3Location": {
                    "Fn::Sub": [
                        "s3://${S3DeploymentBucket}/${S3DeploymentRootKey}/resolvers/Query.nearbyUsers.req.vtl",
                        {
                            "S3DeploymentBucket": {
                                "Ref": "S3DeploymentBucket"
                            },
                            "S3DeploymentRootKey": {
                                "Ref": "S3DeploymentRootKey"
                            }
                        }
                    ]
                },
                "ResponseMappingTemplateS3Location": {
                    "Fn::Sub": [
                        "s3://${S3DeploymentBucket}/${S3DeploymentRootKey}/resolvers/Query.nearbyUsers.res.vtl",
                        {
                            "S3DeploymentBucket": {
                                "Ref": "S3DeploymentBucket"
                            },
                            "S3DeploymentRootKey": {
                                "Ref": "S3DeploymentRootKey"
                            }
                        }
                    ]
                }
            }
        }
    },
    "Conditions": {

    },
    "Outputs": {
    }

}

但是它给了我这个错误：

Resource Name: QueryNearbyUsers (AWS::AppSync::Resolver)
Event Type: create
Reason: No data source found named ElasticsearchDomain (Service: AWSAppSync; Status Code: 404; Error Code: NotFoundException; Request ID: 920993d8-46ef-11e9-82c8-e977f5face03)

我为DataSourceName尝试了许多不同的方法，包括aws控制台中的域名或从其他自动生成的堆栈中复制粘贴代码，...不幸的是，它们都不起作用。

如何找到DataSourceName的值？

似乎，他们的文档中有错字，应该是：

"DataSourceName": "ElasticSearchDomain",

不是：

"DataSourceName": "ElasticsearchDomain",

现在它工作正常。.这么简单的错字浪费了很多时间。
