Box Preview use pdf library and pdf worker they get loaded on demand

[watjs]

I'm using Preview.js version 1.40.0 (https://cdn01.boxcdn.net/platform/preview/1.40.0/en-US/preview.js).

Preview.js loads third-party docs pdf.min.js, pdf.worker.min.js and pdf_viewer from cdn, the link to these JS files are generated according to version inside the library.

I want to check if PDF file is previewable before uploading it to the box, using pdf.js library i can detect wether file is corrupted or protected ( in other word not previewable ).

Does the Preview.js API provides the link to pdf.js library? or the version(1.17.0) used to generate the link?
for example: 'https://cdn01.boxcdn.net/platform/preview/third-party/doc/1.17.0/pdf.worker.min.js'

i want to use the same link that box preview library uses to reduce HTTP and to prevent loading the same library twice.

Thanks in advance.

Found myself in the same situation. Have to use a newer version of pdfjs and I cannot do that apparently.
