EMA C++ subscriber application receive error "Failed to convert to UTF8"

SMR

Hi, Our application is using EMA C++ and sometimes the process crash after receiving refresh/update message. The error message is

[onRefreshMsg: Exception Type='OmmInvalidUsageException', Text='Failed to convert to UTF8 in RmtesBufferImpl::toString(). Reason: RSSL_RET_FAILURE', ErrorCode='-1'(../src/px/pxema/emapriceapp.cxx:169)]

We ran the application in debug mode to identify the FID & associated value but all FIDs seem normal updated. What does this error code mean and is the error due to badly formed update message from the source ?

Thank you.

Thank you for reaching out to us.

I assume that this problem may relate to partial updates. Please refer to the How to parse page-based data using Refinitiv Real-time SDK Java article. This concept is also used in C++.

To handle partial updates, please refer to the 310_MP_Rmtes example.

Thank you for your response. The application subscribes to record based data (cash equity stocks only), no page data. What is meant by partial updates in relation to stocks?

Please share RICs and fileds that cause this issue.

If you have the raw data, I can verify if it is a partial update.
