Exception in parsing google webmasters api response

[Darshan Mehta]

Hello,

I am using google webmasters java client to get the impressions and clicks data over a period of time. However, while executing search analytics query, I get the following exception:

java.lang.IllegalArgumentException: key ctr

Below is the code that I am using to query:

public void testWebmasters(String token){

    try{

         Credential credential = getCredential(token);

         Webmasters service = new Webmasters.Builder(HTTP_TRANSPORT, JSON_FACTORY, credential)

            .setApplicationName("WebmastersCommandLine")

            .build();

    com.google.api.services.webmasters.Webmasters.Sites.List list = service.sites().list();

    SitesListResponse execute = list.execute();

    List<WmxSite> siteEntry = execute.getSiteEntry();

    for(WmxSite site : siteEntry){

    System.out.println(site.getSiteUrl());

    System.out.println(site.getPermissionLevel());

    SearchAnalyticsQueryRequest request = new SearchAnalyticsQueryRequest();

    request.setStartDate("2015-08-01");

    request.setEndDate("2015-08-05");

    request.setDimensions(new ArrayList<String>(){{add("date");}});

    SearchAnalyticsQueryResponse response = service.searchanalytics().query(site.getSiteUrl(), request).execute();

    for(ApiDataRow row : response.getRows()){

    System.out.println(row.getClicks());

    System.out.println(row.getImpressions());

    System.out.println(row.getCtr());

    row.getPosition();

    }

    }

    }catch(Exception e){

    e.printStackTrace();

    }

    }

Below line in the code throws exception:
SearchAnalyticsQueryResponse response = service.searchanalytics().query(site.getSiteUrl(), request).execute();

Going through exception stack trace and code of google java library, it seems this can be resolved by adding @JSONString annotation for 'ctr' property of 'ApiDataRow' class. However, this being a third party library, I don't want to change the code. Also, may be it would fail on another field if I change the code for this.

Any suggestions how to resolve this?

Thanks in advance.
