This is a somewhat misleading (and very rare) error that primarily occurs in the SPOS_Sale script. It occurs when the integration to NetSuite has something wrong with the format that it is expecting. This is around field validation for required fields depending on payment methods.

There is no solution to this error and the transaction will hit the Fail Queue. Once the Fail Queue is processed again, the transaction will error again.

The best way of fixing this is to "send and clear" the Fail Queue logs to your Admin and the Admin will have to manually enter the transaction after reporting it to our Support Team (with a copy of the Fail Queue log file).
