Dear Support,

I use your React Sample to create my program.

When i run “npm start” at the localhost, the IE 11 can 100% success run my program

But i “npm run build” my program and copy the build folder to my IIS server the show the blank page (just only can show meta title)

I m open F12 Developer Tools on IE 11, show 404 file missing of file “lib/webviewer.min.js” and the Console error:

SCRIPT1010: Expected identifier
PDFJSExpress (1,1310849852)

SCRIPT1010: Expected identifier
1.b7a27b1d.chunk.js (1,9643)

I was download and upload “lib/webviewer.min.js” and “lib” folder to my IIS Folder fixed 404 not found but also not work. show the error as below :

SCRIPT1010: Expected identifier
webviewer.min.js (1,1029)

SCRIPT1010: Expected identifier
PDFJSExpress (1,1310849852)

SCRIPT1010: Expected identifier

Hi!

What version of PDF.js Express are you using?

When you open it in a browser that does work, there should be a console log with the version numbers.

Thanks!

Hello Support,

I was fixed the problem.

Remove this line on public/index.html

script src="%PUBLIC_URL%/lib/webviewer.min.js"

Add this meta tab line on public/index.html
meta http-equiv=“X-UA-Compatible” content=“IE=edge”

Also can ref :
