Unable to get IMap data using REST Endpoint

[Rishav Shandilya]

Hi Hazelcast Team,

We have an IMap where key is of type Long. 

Now, I have enabled rest-endpoint group "DATA" in my hz config and  making an api call to fetch that key but getting 204 "No Content" in response.

1. Is there any way of fetching data from IMap with Long key type? (FYI: I am able to fetch data from other maps where key is String?
2. Is there any other endpoint for fetching all map entries in single response? I tried to remove key from URL but that's not giving the desired resp.

GET

Url: http://localhost:5701/hazelcast/rest/maps/${map-name}/100

here: 100 is one of the keys which is present in my map.

We are using Hazelcast 3.12.4
