{{Quickfixn}} Conditionally Required Field Missing (269)

[benjelyn reves]

Please help to shed some light on why I cannot exact the value of 269 (MDEntryType) from the 35=W that we are receiving.20230725-07:36:02.762 : 8=FIX.4.4 9=566 35=W 56=INI-DEMO 49=SERVERDEMO34=994 52=20230725-07:36:02.654 262=20230727073534134USDSGD 55=USD/SGD 167=SPOT 64=20230727 7250=SP 268=6 269=0 270=341.46 271=1000000 278=20230727073534134USDSGD.86.29_B 269=1 270=341.63 271=1000000 278=20230727073534134USdSGD.86.29_B 269=0 270=341.457 271=3000000 278=20230727073534134USDSGD.86.29_C 269=1 270=341.633 271=3000000 278=20230727073534134USDSGD.86.29_C 269=0 270=341.451 271=5000000 278=20230727073534134USDSGD.86.29_D 269=1 270=341.639 271=5000000 278=20230727073534134USDSGD.86.29_D 60=20230725-07:36:02.654 10=044 
Here’s the piece of code I am using:var group =  new QuickFix44.MarketDataSnapshotFullRefresh.NoMDEntries();                MDEntryType MDEntryType = new MDEntryType();                MDEntryPx MDEntryPx = new MDEntryPx();                             message.getGroup(1, group);                group.get(MDEntryType);                group.get(MDEntryPx);                                message.getGroup(2, group);                group.get(MDEntryType);                group.get(MDEntryPx);
I also tried to call like this:mDEntryType = message.getField(new MDEntryType()).getValue();But none of them works.
My application replied 35=j: 20230725-07:36:02.765 : 8=FIX.4.4 9=155 35=j 34=1015 49=INI-DEMO 52=20230725-07:36:02.764 56=SERVERDEMO 263=1 264=0 265=0 45=994 58=Conditionally Required Field Missing (269) 372=W 380=5 10=091 

Please advise how can I extract the value for tag269 and tag270.
