[Koha-bugs] [Bug 34731] C4::Letters::SendQueuedMessages can be triggered with an undef message_id

https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=34731 --- Comment #4 from Kyle M Hall <kyle@bywatersolutions.com> --- We have found a way to recreate this bug. If you update the PASSWORD_CHANGE letter to something like: [%- IF 0 %][% END %] or anything else that would generate a notice, Koha attempts to enqueue the blank notice in Koha::Patron::set_password, but EnqueueLetter returns if the rendered content is empty. Then we call SendQueuedMessages with message_id => undef! This patch set will resolve this issue for the affected code and prevent any regressions. -- You are receiving this mail because: You are watching all bug changes.
