Invalid scope for Youtube API CommentThreads - java

I'm new to Youtube data API and I'm trying to develop a standalone java application on my computer to parse some comments form Youtube videos. The sample code for CommentThreads-list is provided on https://developers.google.com/youtube/v3/docs/commentThreads/list

// Sample Java code for user authorization

        YouTube.CommentThreads.List commentThreadsListByVideoIdRequest = youtube.commentThreads().list(parameters.get("part").toString());

            commentThreadsListByVideoIdRequest.setVideoId(parameters.get("videoId").toString());
        }

        CommentThreadListResponse response = commentThreadsListByVideoIdRequest.execute();
        System.out.println(response);


    } catch (GoogleJsonResponseException e) {
        e.printStackTrace();
        System.err.println("There was a service error: " + e.getDetails().getCode() + " : " + e.getDetails().getMessage());
    } catch (Throwable t) {
        t.printStackTrace();
    }
}
}

After I run the above sample code in eclipse, the browser opens but it shows "Error: invalid_scope". I've attached an image to show this.

As for my OAuth client ID, I created a credential on youtube developer console and I selected "Other" as an Application Type for my project.

I also tried "Web application" and I assigned my localhost http://localhost/Callback for the Authorized redirect URIs. That didn't work either.
