Hello @MayassK

This is not the error but it is field id(FID) 935 definition in a dictionary response received from the server where EMA requests dictionary from(default behavior). I also got the same message as you.

Dictionary request sent from EMA(Outgoing Reactor message)

<!-- Outgoing Reactor message -->
...
<REQUEST domainType="DICTIONARY" streamId="3" containerType="NO_DATA" flags="0x06 (HAS_PRIORITY|STREAMING)" priorityClass="1" priorityCount="1" dataSize="0">

    <dataBody>
    </dataBody>
</REQUEST>

If EMA requests data successfully, you will see the following messages:
