ACK message, nakCode - INVALID_CONTENT, text=Invalid content

We submit events via Refinitiv Real-Time SDK v3.7.1.0 directly to the Refinitiv endpoints (EMA, TunnelStreamRequest, OmmConsumerClient).

In most cases we submit events and get Ok ACK similar to this (according to xml trace output)

However, in some cases which happens usually on a daily basis we get ACK errors to the similar submitted messages, for example

</ACK>
</dataBody>
</GENERIC>

As it can be seen we send messages with the identical format/structure but sometimes get 

nakCode="INVALID_CONTENT" text="Invalid content"

as ACK message.

We are not able to identify the cause of INVALID_CONTENT ACK error messages as from our point of view the outgoing message format is the same and valid.

Any help to get the reason of the problem is highly appreciated.

@JavaDeveloper

Thank you for reaching out to us.

I ran the application to submit the same message to RCC and I got the ACK message properly. However, I sent this post message to the test RIC: TRCCTEST02.

I also found that you have submitted a ticket to the RCC support team to verify what problem is.

I will update this information in the ticket so the support team can verify this issue on the server side.

Thank you @Jirapongse. However, It is still not clear what causes the error as I am still waiting for the answer from RCC support team.
