Can anyone see why this left join isn't working?

select notifications.id, notifications.status, notifications."receiverId", notifications."notificationObjectId"
from 
  notifications
left join 
  "notificationObjects" on notifications."notificationObjectId" = "notificationObjects".id;

select notifications.id, notifications.status, notifications."receiverId", notifications."notificationObjectId"
from 
  notifications
left join 
  "notificationObjects" on notifications."notificationObjectId" = "notificationObjects".id;
