**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?**  
{Every document}

**Link to document**  
{[http://119.29.53.191:7069/download-file-0.0.1/download?fileType=PDF\_DOCUMENT&filePath=/usr/local/rgms-resources/document/de0b2446-7092-4b64-8bba-31dd466e7625\_reading02-07.pdf](http://119.29.53.191:7069/download-file-0.0.1/download?fileType=PDF_DOCUMENT&filePath=/usr/local/rgms-resources/document/de0b2446-7092-4b64-8bba-31dd466e7625_reading02-07.pdf)}

**Code snippet**  
{WebViewer({

// replace with your own PDF file
