Hi! I'm having issues with a freshly installed debian server on which I put a 17.05.06 koha. Plack just won't start. In the logs I had Error while loading /installdir/etc/plack.psgi: Can't load application from file "/gitdir/api/v1/app.pl": Can't locate object method "cache_dir" via package "Swagger2::SchemaValidator" at /usr/share/perl5/Swagger2.pm line 41. After futile attemps, I then "solved" it by upgrading Swagger2 (manually) to 0.89. It "solved" it, then appeared Error while loading /installdir/etc/plack.psgi: Can't load application from file "/gitdir/api/v1/app.pl": Can't locate object method "data" via package "Mojo::URL" at /usr/local/share/perl/5.20.2/Swagger2.pm line 47 Mojo and Mojolicious and everything else I check seem to be at their latest version. No patch from the community (for 17.11+) seem related. Of course, that doesn't happen on my other servers, but they are "old", so somewhere a .pm is different for sure.
