Error
{#
I'd like to use ``build.error|urlize`` here, so we can have nice links.
However, this is not possible because we are using `data-bind="text: error"`
which means that Knockout.js will use the `.error` attribute to fill
the content of this tag dynamically.

Build output directory for format "pdf" contains multiple files and it is not currently supported. Please, remove all the files but the "pdf" you want to upload.
