Swagger error: [unable to parse as json; raw response below]

[RGBD]

Posting the following flow below it appears in the controller, but I get this error message:

 [unable to parse as json; raw response below]

Flare version:  01.13.00.2877

Flow json is:

{"flow": {
    "priority": 30000,
    "idle_timeout": 10,
      "match": [
        {
          "in_port": 13
        }
      ],
    "actions": [{"output": 14}]
}}

Returned flow from controller:

{
  "version": "1.0.0",
  "flows": [
    {
      "duration_sec": 300,
      "duration_nsec": 4000,
      "priority": 30000,
      "idle_timeout": 10,
      "hard_timeout": 0,
      "cookie": "0x0",
      "packet_count": 2341,
      "byte_count": 134232425,
      "match": [
        {
          "in_port": 13
        }
      ],
      "actions": [
        {
          "output": 14
        }
      ]
    }
  ]
}

Which OpenFlow switch are you using?

If switch uses OpenFlow 1.3, you have to use 1.3 notation.

Can you provide/point to OF v1.0 format?

 From flow response it looks like switch supports openflow version1.0.0 (This can be verified by getting all datapaths from Swagger UI. Check the negotiated_version in response json) 

Please let me know which of the following steps fail while adding a flow.

1) Posting the following flow from Swagger UI:

{"flow": {
    "priority": 30000,
    "idle_timeout": 10,
      "match": [
        {
          "in_port": 13
        }
      ],
    "actions": [{"output": 14}]
}}

Response from the controller

          Response code : 201

          Response Body : [unable to parse as json; raw response below]

(Actual response body for this action is nothing)

3) Verifying if the flow is added on the datapath.

4) Getting flows for the datapath from Swagger UI

Response:

 
{
  "version": "1.0.0",
  "flows": [
    {
      "duration_sec": 300,
      "duration_nsec": 4000,
      "priority": 30000,
      "idle_timeout": 10,
      "hard_timeout": 0,
      "cookie": "0x0",
      "packet_count": 2341,
      "byte_count": 134232425,
      "match": [
        {
          "in_port": 13
        }
      ],
      "actions": [
        {
          "output": 14
        }
      ]
    }
  ]
}

I tried to insert the suggested flow from swagger UI. I can see the flow on controller and datapath. But UI returns an error [unable to parse as json; raw response below] in response body with a response code of 201 (created).

For now, Please ignore the error string. Swagger UI is trying to parse an empty Json response and fails. This has no impact on flow insertion.
