**PDF.js Express Version**

**Detailed description of issue**  
{When I download the Vue Demo on the website, I replace the default file path to my own file path, But  
it just can’t work. The console of Chrome give me the error info:“Access to fecth ‘url’ has been blocked by CORS policy”}. It means that the url is on another remote server, pdf.js express can’t open it. However, I have solved the CORS problem to make sure every file can be fetched from every request. I can open the same file in Chrome or any other pdf viewer software. Can anyone help me?

**Expected behaviour**  
{I expecte to open the remote file by url in a Vue Project.}

**Does your issue happen with every document, or just one?**

Hi there,

The URL you provided leads to an error page, so I’m guessing that that’s the problem. Please make sure your document is available at that URL.

Thanks!
