https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=20084 --- Comment #1 from Victor Grousset/tuxayo <victor.grousset@biblibre.com> --- ## Reproduction ## This is an oversimplification of a full patron card setup used in production. 1. Create a batch with 1 patron 2. Create a layout and set the name "Print card number as barcode" "Barcode type:" to "Code 39" 3. Create a card template without filling anything 4. Export the batch using the layout and template 5. You should have a white page with a barcode And no errors in the relevant log file This show that this setup isn't completely bogus (although Code 39 is the only type working) 6. Layout: set "Barcode type:" to Industrial2of5 7. Export the batch 8. You should have a white page with no barcode And errors in the relevant log file "Invalid Characters" ## going further ## COOP2of5 fails also with the same error TODO: Fix at the same time or open another bug -- You are receiving this mail because: You are watching all bug changes.
