Such a modification is (obviously) not supported, see PR #6916 for additional details. Furthermore it's quite likely that you, as is already explained in the FAQ (see https://github.com/mozilla/pdf.js/wiki/Frequently-Asked-Questions#faq-xhr), are running into CORS issues.

However, it's unfortunately somewhat difficult to understand exactly what you're actually trying to ask/report here!
Please rephrase your question/issue, by providing clear and concise steps to reproduce the problem. Furthermore, please see https://github.com/mozilla/pdf.js/blob/master/.github/CONTRIBUTING.md (emphasis mine):

If you are developing a custom solution, first check the examples at https://github.com/mozilla/pdf.js#learning and search existing issues. If this does not help, please prepare a short well-documented example that demonstrates the problem and make it accessible online on your website, JS Bin, GitHub, etc. before opening a new issue or contacting us on the IRC channel -- keep in mind that just code snippets won't help us troubleshoot the problem.#

I agree with the above. The PDF file works fine with the default viewer, so it's most likely a CORS issue.
