Data logger problem with LLONG variable

Hello community,

I am reading via OPCUA a variable LLONG. on the OPC Client simulation the variable is visible. 

when I try to add this variable to the DATA LOGGER , and create a dedicate table for this type of data, there is no way to be able to write on SQL table and start the LOG. 

the alarm is 

Date Time Level Source Event
11/11/2024 4:59:19 PM Warning Data Logger Plug-in Failed to register log item 'LogItem1' for log group 'LOG_SCADA_LLONG'.

apparently there is no other messages. I setup a LONG value, from a similar or identical OPC device and there was clear indication of the issue. 

if anyone has an idea , appreciate.

Thanks
