WebViewer not getting loaded in IE11 and Safari browsers

Technical Support
#1

Hi Logan,

As per your comment on the old ticket: “However, if you can provide an error message that originates from PDF.js Express , please feel free to share it in a new thread and we can investigate further.”, I am generating new topic for my IE11 Webviewer issue.

PFA of webviewer does not loaded in IE11, and showing some “Invalid Character” Error, most probably due to the pagination numbers not loaded fully.

Please note that, The Webviewer is successfully loaded on Chrome, Firefox, Edge, Opera browser., however does not loaded in IE11 and Safari browser. Also we have upgraded PDFjs Express with v.7.2.

So, If there could be a issue in my application, then it should not work in other browsers too, however it has been working fine except IE11 and Safari

Kindly advice.

Warm Regards

Hi,

The issue would be that your code is not transpiled to work in these browsers that do not support ES6 syntax. PDF.js Express is transpiled to work in these environments, and is heavily tested in these environments (as proven by the link I sent in my previous post).

Please make sure your JS is getting transpiled to work in these browsers.

Hi Logan,

I had already transpiled the code supported to IE 11 and Safari browsers, that’s the reason webviewer is getting loaded half-way, otherwise the webviewer was not even loaded half-way.

If you are ready to check and help, then let me know I can share the transpiled code.

Warm Regards

Hi,

Unfortunately, looking at transpiled code will not help much. Could you provide me a URL to to your app so I can take a look at it in IE and see where the error is coming from?

If that is not possible, can you send a screen shot of where the error message is coming from? This means clicking into the error message and actually viewing the code where the error is coming from.

Thanks,
Logan

Thanks that worked.

The viewer is getting loaded on the web page you provided, and I do not see any errors coming from Express in the console. This means that the viewer is being loaded correctly and the issue is on your end, probably related to how you are loading the document,

I see an error from the AWS SDK RangeError: Invalid Date — only in Safari and IE. My guess is that this is probably the cause of the issue.

Thanks,
Logan

Also, Are you getting a same error in I.E too?

Hi,

The screenshot is clear on my end, I can’t get it any clearer.

I do see this error in IE11 as well.

I can confirm that the error is not coming from PDF.js Express, so I will close this issue.

If you can provide an error message originating from PDF.js Express, please open a new bug report.

Thanks!
Logan
