Read_lease doesn't return lease_id

[inikolaev]

While using the library I noticed that read_lease functions returns lease_id as an empty string and lease_duration always set to zero:

{
  "request_id": "d352cca8-fe53-46cd-ad8c-a93abbe7386d", 
  "lease_id": "", 
  "renewable": false, 
  "lease_duration": 0, 
  "data": {
    "expire_time": "2020-05-23T22:52:00.92184119Z", 
    "id": "<lease-id>", 
    "issue_time": "2020-05-23T22:11:59.122046526Z", 
    "last_renewal": "2020-05-23T22:22:00.921841304Z", 
    "renewable": true, 
    "ttl": 1105
  }, 
  "wrap_info": null, 
  "warnings": null, 
  "auth": null
}

Is that expected? Looks very odd.
