[Koha] Error Printing Library Cards in Koha

Hello Colleagues,  I have the attached error while trying to print out a batch of 200 cards from Koha. A batch because some scripts were written to pull records directly from our university database to Koha and the records were batched for the importation of the cards into Koha. While other batches print successfully, a particular batch gives the attached error. I have attached a picture of the error and the log file view. Please I need help as to how to resolve this. Your help will be appreciated please. Olufunmilayo FATISystems Programmer/Systems Librarian Federal University of Agriculture Abeokuta, Nigeria
