https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=30949 Bug ID: 30949 Summary: Error 500 in z3950_search.pl Change sponsored?: --- Product: Koha Version: 22.05 Hardware: All OS: All Status: NEW Severity: normal Priority: P5 - low Component: Cataloging Assignee: koha-bugs@lists.koha-community.org Reporter: egpetridis@yahoo.com QA Contact: testopia@bugs.koha-community.org CC: m.de.rooy@rijksmuseum.nl Created attachment 135974 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=135974&action=edit koha intranet error I wonder how may one debug errors 500 in z3950_search.pl, especially when searching against multiple targets. Searching for ISSN 1061-2688 in the following targets (among many others) host: webcat.lib.unc.edu port: 210 DB: innopac host: afton.lib.unc.edu port: 210 DB: INNOPAC I get the following error: Home Error 500 An error has occurred! Error 500 This message may have been caused by any of the following reasons: You made use of an external link to an item that is no longer available You followed an outdated link e.g. from a search engine or a bookmark You tried to access a page that needs authentication An internal link in the client is broken and the page does not exist What's next? Use top menu bar to navigate to another part of Koha. To report a broken link or any other issue, please contact the Koha administrator. Send email Error logs to be uploaded. Please don't focus on the server mentioned in them, as I located the servers above in previous tries but decided to file a bug report on subsequent searches that produced said error. In different previous searches I've encountered the same problem while searching against targets host: NLS.ALMA.EXLIBRISGROUP.COM port: 210 DB: 44NLS_INST (https://www.nls.uk/catalogues/z39-50/) host: ELIBRARY.MEL.ORG port: 210 DB: INNOPAC for example. Again, these are merely the targets I had managed to narrow down in the past. I noticed that tag 915 is mentioned in the logs (...Field 915 must have at least one subfield...), whereas no such tag is defined in standard koha frameworks such as BKS and SER. Could this be the culprit, data that koha doesn't expect to receive? Those very targets work fine when queried for different books/magazines, so it must be something contained in specific results. The error may also have to do with the fact that all Z39.50 servers defined in my installation have "Del952.xsl,Del9LinksExcept952.xsl" in the "XSLT File(s) for transforming results" field. Both XSLT files are stock, as provided in a packages installation. Some 10 years ago I had made the same question, but got nowhere. https://lists.katipo.co.nz/public/koha/2012-August/033847.html -- You are receiving this mail because: You are watching all bug changes.
