Hi, it believe is because 4780000000000 is not valid EAN13 - the exception says it all InvalidCheckDigitException
Your 4780000000000 is not valid, check digit is 7, therefore 4780000000007 is valid EAN13.
You can calculate online for example on https://www.gs1.org/services/check-digit-calculator or use some formulas that can be found on internet.

Yep, JanMikes is right. It is not a valid EAN13 number. You can create a Code128 barcode if you really want 4780000000000 in the barcode. But it is not valid if you want EAN13.
