[adamramage]

MongooseIM version: 6.1.0-549-gcd8a52f4d Installed from: Docker - mongooseim/mongooseim:PR-4149

Describe the issue. GraphQL Session listSessions returns an empty list.

Executing the following returns varying results indicating the graphql query to return listSessions may be broken

Below shows a list of connected users as i would expect

root@ctl00:/# mongooseimctl connected_users_info
62117800748.iq3@my.domain.example.com/iq3      c2s_tls 127.0.0.1       47010   0       mongooseim@pub00-2c.xmpp.my.domain.example.com    74758

Below returns a count of connected users as i would expect

root@ctl00:/# mongooseimctl graphql 'query {session {countSessions}}'
{
  "data" : {
    "session" : {
      "countSessions" : 1
    }
  }
}

Below returns a count of connected users as i would expect when the domain is provided

root@ctl00:/# mongooseimctl graphql 'query {session {countSessions(domain: "my.domain.example.com")}}'
{
  "data" : {
    "session" : {
      "countSessions" : 1
    }
  }
}

Below returns an empty list when the domain is provided

root@ctl00:/# mongooseimctl graphql 'query {session {listSessions(domain: "my.domain.example.com")}}'
{
  "data" : {
    "session" : {
      "listSessions" : [
        {

        }
      ]
    }
  }
}

Below returns an empty list when the domain field is not entered

root@ctl00:/# mongooseimctl graphql 'query {session {listSessions}}'
{
  "data" : {
    "session" : {
      "listSessions" : [
        {

        }
      ]
    }
  }
}
