[Quickfix-users] Tag Not defined For This message type

[Lanxin Z. <lzh...@gm...>]

Hi,
I am using the QuickFix in a client connecting to a FIX.4.4 server. But it
is rejecting an incoming message from the server.
The incoming message is a market data incremental refresh message (type
'X'):
8=FIX.4.4 9=0176 35=X 49=Server 56=Client 52=20230308-22:19:58.392 34=7245
268=2
    279=0 55=2yr-3yr 269=0 270=-33.5575551979 271=0 1500=90
    279=0 55=2yr-3yr 269=1 270=-31.3489011553 271=0 1500=90 10=034
However The client generated a reject message like this: 58=Tag not defined
for this message type 371=55 372=X
Here is the spec and configuration i am using:
DefaultApplVerID=FIX.4.4
ConnectionType=initiator
BeginString=FIX.4.4
UseDataDictionary=Y
DataDictionary=path/spec/FIX44.xml
FileStorePath=./Sessions/
ValidateIncomingMessage=N
ValidateUserDefinedFields=N
ValidateFieldsOutOfOrder=N
RejectInvalidMessage=N

  <field number='278' name='MDEntryID' type='STRING' />
 <field number='346' name='NumberOfOrders' type='INT' />
 <field number='1500' name='MDStreamID' type='INT'/>

I verified my code is properly loading the 4.4 xml file.

I was wondering if anyone had encountered this before and if they knew
how to resolve it?

Many thanks in advance.
