Why am I receiving this ADF_FACES-60097/96 when defaulting payroll when converting pending worker?

Summary:

Autocomplete object defaulting rule to default payrollID based on Legal Entity and some assignment attributes is working for Hire Employee. When adding employee through the pending worker page, rules fails with ADF_FACES error.

Content (required):

We are checking to ensure with HCM Params that this is for new hire and apparently converting pending workers falls within this area as well which is fine but why do we get the error?

Customer Name is YRC Enterprise Services Inc and Use case #3

Thanks.
