Ebook Import dialogue displays success message even when there's a server-side error #459
Description
In this instance, the book did not import, but the success message was still displayed.
There should be some more robust error handling to catch any server-side errors in the imports to properly display error messages to the user.
Note: this was during some experimentation on the Python service, so it isn't an active bug or anything, but still would be good to have in the event of any actual server-side errors.
