Error while posting new flow

Hi experts,

I'm having some troubles while trying to post some flows using a Python script to the VAN SDN Controller.
I'm just trying for now a very basic POST request, applying a new output port, based on the Source IP and Eth Type.

{
   "flow":{
      "priority":50000,
      "hard_timeout":60,
      "table_id":100,
      "flow_mod_flags": ["send_flow_rem"],
      "match":[
         {
            "ipv4_src": "10.105.211.11"
         },
         {
            "eth_type": "ipv4"
         },
         {
            "in_port": 4
         }
       ],
       "instructions":[
         {
            "apply_actions":[
               {
                  "output":1
               }
            ]
         }
       ]
    }
}

Unfortunately, I get an error from the Controller :

"error": "java.lang.IllegalArgumentException",
"message": "Failed to validate flowmod: {ofm:[V_1_3,FLOW_MOD,96,1394077],cmd=ADD,match={Match(V_1_3):[type=OXM,len=18],fields=ETH_TYPE,IPV4_SRC},...}"

I tried with an empty POST request, to block flows from a client, and it works fine.
I've already change the table_id, trying table 100 and 200, but still get this issue.

Knowing that the ultimate goal of this script is to redirect a packet to a new IP dest, with the following JSON code :

		"instructions": [{
			"apply_actions": [{
				"set_field": {
					"ipv4_dst": "10.105.100.1"
				}
			}, {
				"output": 1
			}]
		}]

Does anyone already get this error, and how to fix it ?
VAN is in 2.7.18.0503 release, and switch is 2930F 8 ports in 16.03 release.

Thanks a lot for your suggestions.
