==== What is the problem?//As a Wikisource user, I want the error with w:<title> to be fixed, so that books that were previously accessible via download can be downloaded again.
There are a few books which don't export, returning instead the error://
**Background: **There are a few books which don't export, returning instead the error:
`Page not found for: w:<title>` This seems to have occurred due to our work in T264788.
