Fix random page not found error from suggestion search

Clicking on some documents from the suggestion search gives a page not found.
It doesn't seem to be all documents of a certain type (some workspaces give a page not found, some don't, some users do, some don't...).

However, here are the URLs of some page not found when I click on documents from the suggestion:
