I had the same issue yesterday at the head of the git depot.(https://github.com/adaptlearning/adapt_authoring)
That error was preventing me to display any courses.
I figured out that problem was the "&operators%5Bsort%5D%5Btitle%5D=1" part of the url.
After some debugging, I commented out the line "sort: this.sort" in dashboardView.js:240 and it worked as a temporary fix.
Hope this could help.
