Appsync created with CDK, Query not showing results

Hello,

I understand that you have created AppSync API using CDK, which is returning null response for listMyTables query.

Here is a blogpost example on creating AppSync API, using CDK:

https://aws.amazon.com/blogs/mobile/building-scalable-graphql-apis-on-aws-with-cdk-and-aws-appsync/

In order to troubleshoot this issue, we require details that are specific to AppSync API deployment in your account. We need to evaluate schema definition, resolver, data source, permissions and AppSync logs for your API. Please open a support case with AWS, including these details, using this link

Thank you Isha. I opened a support case and received a helpful answer. I ended up having to provide more detail in my resolver. I copied the code that was generated in the "console" created api, and pasted it in like below. With this change, the API functioned as expected:

change from this:

datasource.createResolver({
        typeName: 'Query',
        fieldName: 'listCctSharedCallRoutingGlobalDbs',
        requestMappingTemplate: MappingTemplate.dynamoDbScanTable(),
        responseMappingTemplate: MappingTemplate.dynamoDbResultList(),
      });

to this:

datasource.createResolver({
      typeName: 'Query',
      fieldName: 'listCctSharedCallRoutingGlobalDbs',
      requestMappingTemplate: MappingTemplate.fromString(`
      #set( $ListRequest = {
        "version": "2018-05-29"
      } )
      #if( $context.args.nextToken )
        #set( $ListRequest.nextToken = $context.args.nextToken )
      #end
      #if( $context.args.limit )
        #set( $ListRequest.limit = $context.args.limit )
      #end
      $util.qr($ListRequest.put("operation", "Scan"))
      $util.toJson($ListRequest)
    `),
      responseMappingTemplate: MappingTemplate.fromString(`
      #if( $ctx.error)
        $util.error($ctx.error.message, $ctx.error.type)
      #else
        $util.toJson($ctx.result)
      #end
      `),
    });
