{{Quickfixn}} Field 35 not found when connecting using FIX.5.0SP2

[Francis Gingras]

Hi,

I am having trouble connecting to a counterparty using FIX.5.0SP2 with
QuickFix/n 1.10.1.0. I must be missing something obvious, but I can't see
it. I get "QuickFix.FieldNotFoundException: field not found for tag: 35".

Config file:
[DEFAULT]
ConnectionType=initiator
BeginString=FIXT.1.1
DefaultApplVerID=FIX.5.0SP2
TransportDataDictionary=FIXT11.xml
AppDataDictionary=FIX50SP2.xml
ReconnectInterval=30
FileStorePath=C:\Store
FileLogPath=C:\Fix
HeartBtInt=20
LogonTimeout=15
TimeZone=Eastern Standard Time
IgnorePossDupResendRequests=Y
StartTime=16:45:00
EndTime=18:00:00
StartDay=sun
EndDay=fri
UseDataDictionary=Y
ValidateUserDefinedFields=N
ValidateFieldsHaveValues=N
ResetOnLogout=N
ResetOnDisconnect=N
CheckLatency=N
RequiresOrigSendingTime=N
PersistMessages=Y
[SESSION]
SenderCompID=APItest
TargetCompID=FIX1
SocketConnectHost=blabla
SocketConnectPort=7002

Code:
SessionSettings sessionSettings = new
SessionSettings($@"{QuickFIXSettingsFileName}");
QuickFix.FIX50SP2.MessageFactory messageFactory = new
QuickFix.FIX50SP2.MessageFactory();
FileStoreFactory storeFactory = new FileStoreFactory(sessionSettings);
FileLogFactory logFactory = new FileLogFactory(sessionSettings);
socket = new QuickFix.Transport.SocketInitiator(this, storeFactory,
sessionSettings, logFactory, messageFactory);
socket.Start();

QuickFix.MessageCracker interface is implemented, but I do not get any
messages there. Is there a different interface I must implement for FIX5?

FIXT.1.1- APItest-FIX1.event.current.log:
Connection succeeded
Unexpected exception: QuickFix.FieldNotFoundException: field not found for
tag: 35
   at QuickFix.FieldMap.GetString(Int32 tag)
   at QuickFix.Session.SendRaw(Message message, Int32 seqNum)
   at QuickFix.Session.GenerateLogon()
   at QuickFix.Session.Next()
   at QuickFix.Transport.SocketInitiator.SocketInitiatorThreadStart(Object
socketInitiatorThread)

File store only has data in the session file:
20221107-16:41:39.692332 Z

The dictionary file has the standard 5.0 definition for Logon:
    <message name="Logon" msgtype="A" msgcat="admin">
      <field name="EncryptMethod" required="Y"/>
      <field name="HeartBtInt" required="Y"/>
      <field name="RawDataLength" required="N"/>
      <field name="RawData" required="N"/>
      <field name="ResetSeqNumFlag" required="N"/>
      <field name="NextExpectedMsgSeqNum" required="N"/>
      <field name="MaxMessageSize" required="N"/>
      <component name="MsgTypeGrp" required="N"/>
      <field name="TestMessageIndicator" required="N"/>
      <field name="Username" required="N"/>
      <field name="Password" required="N"/>
      <field name="NewPassword" required="N"/>
      <field name="EncryptedPasswordMethod" required="N"/>
      <field name="EncryptedPasswordLen" required="N"/>
      <field name="EncryptedPassword" required="N"/>
      <field name="EncryptedNewPasswordLen" required="N"/>
      <field name="EncryptedNewPassword" required="N"/>
      <field name="SessionStatus" required="N"/>
      <field name="DefaultApplVerID" required="Y"/>
      <field name="DefaultApplExtID" required="N"/>
      <field name="DefaultCstmApplVerID" required="N"/>
      <field name="Text" required="N"/>
      <field name="EncodedTextLen" required="N"/>
      <field name="EncodedText" required="N"/>
    </message>

Thanks!
