Unable to test CRUD

[jAddict7]

I have created tables in DynamoDB as required and made the code run. But am unable to test finder methods as it contains objects as input. Can I get some sample URL for searching contents.

http://localhost:8080/replies/search/findByThreadIdOrderByReplyDateTimeDesc%7B?threadId,page,size,sort}
