Created attachment 172100 [details] Screenshot of the bug There are 2 bugs to report. One, which already seems to be reported is, empty fields while editing identity provider in 24.05+ (main reason why koha was not updated and we sticked to stable 23.11) Another bug is related to opening IDP API URL directly in browser such as <baseurl>/api/v1/public/oauth/login/<code>/opac which returns the following result in fresh/incognito session with no stored cookies (as in 23.11.08): { "errors": [ { "message": "Internal Server Error.", "path": "/" } ], "status": 500 } The expected behavior should be redirecting to IDP page (which actually works fine when there are stored browser cookies due to visiting koha homepage for the first time and then trying this link).
