Found under 21.11 Can't use an undefined value as a HASH reference at /usr/share/koha/mainpage.pl line 87 Log shows: [02/Nov/2022:08:36:51 +0100] "POST /intranet/mainpage.pl HTTP/1.1" 500 41624 Line 87: my $local_pendingsuggestions_count = $pendingsuggestions->search({ 'me.branchcode' => C4::Context->userenv()->{'branch'} })->count(); Note: In master this is line 88. Apparently there is no user context. So no branch key. But when you get here, you came thru Auth.pm. So we should expect one? Could not find a way to reproduce this one yet.
