SuiteCRM 7.1.4 - Error while duplicating records

Hi there,
on a SuiteCRM 7.1.4 i found this error while duplicating a record even as an admin user:

In this example i am duplicating an account:

If i click “Save” or “Cancel” , it doesn’t matter,
i got this error:

I also find this error trying to merge records.

Do you know wich can be the problem?

It might worth checking the error logs to see if there is anything recorded in there when this error happens,

Ian.
