The XID cannot be generated error in AJO Push dataset

Greeting Adobe Community!

I am observing the following error code 

and here are the details of the error - 

“The XID cannot be generated for code userId.XID generation failed for nsCode = {code}, nsId = {id}”

I am getting similar error messages in the AJO Push Profile Dataset while testing push notifications for different fields where all ingestions are failing due as XID cannot be generated. Has anyone faced the same? Any guidance and support would be really appreciated. 

Thanks,
Sambit
