https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=32399 --- Comment #1 from Katrin Fischer <katrin.fischer@bsz-bw.de> --- While we first thought this to be a data issue, it might not be the case, from the mailing list: Nope. In fact, issues has only one row, with its integer on borrowernumber: issue_id: 2. borrowernumber: 53805. issuer_id: NULL. itemnumber: 1581. date_due: 2020-10-08 23:59:00. branchcode: BC. returndate: NULL. lastreneweddate: NULL. renewals: 0. unseen_renewals: 0. auto_renew: 0. auto_renew_error: NULL. timestamp: 2020-10-07 15:29:52. issuedate: 2020-10-07 borrowernumber (and itemnumber) are not NULL in the only row of issues table. Also, the borrowernumber (53805) exists on borrowers table. Could be something else? -- You are receiving this mail because: You are the assignee for the bug. You are watching all bug changes.
