Trex exception attribute value is not a number

Hi,

In one of the applications on the portal (which is on NW 7.3), we are using Trex and when we try to search for anything, it gives the following exception:

com.sapportals.trex.TrexException: attribute value is not a number;index=dealerinventorytrader_index,location=epdidc02:30203 (Errorcode 6930)

I am not familiar with KM and Trex and am trying to find out what is causing the issue. I have checked the status of the index in the system administration and it shows green. Also, in the queue status, it shows idle for this index.

Thanks & Regards,
