Getting NAK posting via TSA using websocket api "UpdateMsg has no RSSL_UPMF_HAS_MSG_KEY flag"

billr

Hi

I'm trying to use the Websocket API to make an off-stream post using a TREP service configured for TSA to TRCC. Currently I receive the following error

"NakCode":"DeniedBySrc", "Text":"UpdateMsg has no RSSL_UPMF_HAS_MSG_KEY flag",

Below is an extract of the message structure which is based on the code provided in the posting example for the Websocket API:

mp_post_json = {

    'ID': 1,
    'Type':'Post',
    'Domain':'MarketPrice',
    'Key': {

        'Name': 'EAASTEST01',
        'Service':'TSA_SERVICE'},
    'Ack':True,
    'PostID': post_id,
    'PostUserInfo': {

        'Address':position,  # Use IP address as the Post User Address.
	'UserID':os.getpid() # Use process ID as the Post User Id.},
    'Message': {

        'ID': 0,
        'Type':'Update',
        'Solicited': True,
        'Fields':{'BID':45.55,
                  'BIDSIZE':18,
                  'ASK':45.57,
                  'ASKSIZE':19}
    }
}

Thanks,

Bill

Hi @billr, Sorry for the delay, the key has to be included in the encoded update message. This update message works for me for contributing to TSA:

var msg = {
  "ID": 1,
  "Type": "Post",
  "Domain": "MarketPrice",
  "Ack": true,
  "PostID": postId,
  "PostUserInfo": {
    "Address": "127.0.0.1",
    "UserID": 5324
  },
  "Key": {
    "Name": "*****",
    "Service": "****"
  },
  "Message": {
    "Domain": "MarketPrice",
    "ID": 0,
    "Type": "Update",
    "Fields": {
      "BID": 45.55
    },
    "Key": {
      "Name": "****",
      "Service": "****"
    }
  }
};

Let me know if it doesn't work for you. Thanks.

Hi @billr Can you confirm that your user ID is allowed to post to TRCC service to these fields, and that off-stream posting is correctly configured in ADS (no errors in ADS log).

Hi @Gurpreet. Yes I should be able to contribute to these FIDs, but to simplify things a little I have cut the FID list to just BID(22). Also I'm not sure what I see seems to reflect an issue with entitlement, but I'm new to TSA/TRCC so not 100%.

No errors in the ADS or ADH logs, but if I set trace for the source session on the ADH(session rsslReactor.1) the message reflects what I see at the client. Looking at what I sent 'updateType="0 (RDM_UPD_EVENT_TYPE_UNSPECIFIED)"' seems to be relevant. Looks like I'm just missing a key or have misconstructed the post message.
