Duplicate Key name for federation link channels

[prasanth kumar]

Hi Team,

We are using RabbitMQ version: 3.12.6 and Erlang/OTP 25 on top of RedHat 8.

For /api/consumers/<VHOST> API we are getting a empty channel object for federation link channel. Due to this few JAVA modules are considering it as invalid json due to duplicate key name and failed to parse the json response received for consumers HTTP API. 

channel response:

   {
      "arguments":{
         "x-priority":-1
      },
      "ack_required":true,
      "active":true,
      "activity_status":"up",
      "channel_details":[
         
      ],
      "channel_details":{
         "connection_name":"x.x.x.x:x.x.x.x -> x.x.x.x:x.x.x.x",
         "name":"x.x.x.x:x.x.x.x -> x.x.x.x:x.x.x.x (1)",
         "node":"rmq1",
         "number":1,
         "peer_host":"x.x.x.x",
         "peer_port":x.x.x.x.,
         "user":"x.x.x.x"
      },
      "consumer_tag":"upstreamfederation",
      "consumer_timeout":1800000,
      "exclusive":false,
      "prefetch_count":50,
      "queue":{
         "name":"queuename",
         "vhost":"vhost"
      }
   },

Error from JAVA: org.json.JSONArray

Exception in thread "main" org.json.JSONException: Duplicate key "channel_details" at 159 [character 20 line 9]
    at org.json.JSONTokener.syntaxError(JSONTokener.java:521)
