Hi Doug Those kinds of errors usually are "safe" to ignore.They usually come from a function that is expecting a value in a variable/parameter, but there is no value. For example, a function that passes barcode as reference or to a next process but the item you are working with does not have a barcode defined.
Sometimes those are minor bugs that, due to a variable/parameter not "cleaned/evaluated" correctly before using it, gives those kinds of errors. In the example above, function shall check if barcode is defined before trying to use it somewhere after. If you have checked the last version 20 update notice, there are several similar errors where an operation is tried to perform on an empty value. https://koha-community.org/koha-20-11-03-released/ in other bugs -> circulation In any case, it is a good idea to check what you are doing when that happens to try to pinpoint the problem.
