error - "Launch could not be promoted"
I created a launch of our homepage and made my edits. When I go to Promote Launch from sidekick I get an error message "Launch could not be promoted". Then if I refresh the page my edits get overwritten by the production page. I do not see anything showing in my error logs or any of my logs related to this. What could be going on and how do I resolve this?
A little extra context. We are using AEM 5.6.1 and this did work back in December but suddenly stopped working.
