I am currently working on an UI for Kapua to resemble the user experience from another project we´ve did early this year. While doing so, I am failing in writing to an asset channel using the endpoint `v1/_/devices/AgE72ry2B3c/assets/_write`. The body I am sending looks like this:

{
  "assets": [
    {
      "name": "Display",
      "channels": [
        {
          "mode": "WRITE",
          "name": "Segment",
          "value": {}
        }
      ]
    }
  ]
}

and I receive the following response:

{
  "type": "kapuaExceptionInfo",
  "httpErrorCode": 500,
  "message": "Error: BAD_REQUEST, Generic Error - BAD_REQUEST: {1}, org.eclipse.kura.KuraException: Generic Error - BAD_REQUEST: {1}\n\tat org.eclipse.kura.internal.asset.cloudlet.AssetCloudlet.write(AssetCloudlet.java:305)\n\tat org.eclipse.kura.internal.asset.cloudlet.AssetCloudlet.doExec(AssetCloudlet.java:206)\n\tat org.eclipse.kura.core.cloud.MessageHandlerCallable.call(MessageHandlerCallable.java:139)\n\tat org.eclipse.kura.core.cloud.MessageHandlerCallable.call(MessageHandlerCallable.java:1)\n\tat java.util.concurrent.FutureTask.run(FutureTask.java:266)\n\tat java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149)\n\tat java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624)\n\tat java.lang.Thread.run(Thread.java:748)\n, [Ljava.lang.Object;@32dc4f51",
  "kapuaErrorCode": "ASSET_WRITE_ERROR"
}

Maybe someone did the same and found a solution...

According to @lorthirk in gitter, to write an asset the format of the body should be:

{
  "type": "deviceAssets",
  "deviceAsset": [
    {
      "name": "asset2",
      "channels": [
        {
          "valueType": "integer",
          "value": 5,
          "name": "Channel-1"
        },
        {
          "valueType": "integer",
          "value": 8,
          "name": "Channel-3"
        }
      ]
    }
  ]
}

Hope it helps!

Pedro
