Custom geolocation search resolver using aws-amplify api - amazon-web-services

Question

I'm trying to add a custom geolocation search resolver that targets an Elasticsearch domain using aws-amplify API (base on documentation)
My Custom stack json is :
{
"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": {
}
}
But It give me this error :
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)
I tried many different things for DataSourceName including the domain name in aws console or copy pasting the code from other auto generated stacks,... unfortunately none of them work .
How can I find DataSourceName value?

Seems, there is a typo in their documentation and it should be :
"DataSourceName": "ElasticSearchDomain",
not :
"DataSourceName": "ElasticsearchDomain",
now it's working fine.. so many hours wasted on such a simple typo.
