Dual write initial sync error

Hi all,

I am getting the following error while doing inital sync activity for a data entity: Reason: Bad Request, Header x-ms-client-request-id ####, Error code: 0x80040265, Message: OrganizationServiceFault. The sync does not start the DW run, only 1 record fails and I can see a warning. This happens in the first run, & in the next data sync it starts fine. This is observed in most of the environments and also its not happening for the same record hence seems not to be a data issue. Since this is happening always, does anyone has any idea how to resolve this? I have tried clearing the cache as well.
