How do I resolve the error - Invalid or Blank Ship To / Ship From Postal code?

The Ship To postal code is validated against the GTSIN. The Ship To postal code must be from the same state as the GSTIN. 

The Ship From postal code is validated against the C_GSTIN. The Ship To postal code must be from the same state as the GSTIN.

Please ensure that you have valid Ship To and Ship From Postal codes present.
