https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=35614 --- Comment #5 from Tomás Cohen Arazi <tomascohen@gmail.com> --- We were having a weird error on a spec regarding collectionFormat and we noticed https://github.com/jhthorsen/mojolicious-plugin-openapi/commit/c972fdd02a05d... Because after updating the updated library the problem went away. To reproduce: 1. Point your REST client to /api/v1/holds 2. Pass x-koha-embed: pickup_library => SUCCESS: You get the results 3. Pass x-koha-embed: biblio => SUCCSS: You get results 4. Pass x-koha-embed: pickup_library,biblio => FAIL: Weird and inconsistent error (i.e. it tells you valid options are... what we passed) 5. Update the library 6. Repeat 4 => SUCCESS: It now works -- You are receiving this mail because: You are watching all bug changes.
