Hi guys,

This error is coming from inside the pdf.js library we are using internally - I tested it out on the latest upstream version of pdf.js and it does not throw this warning. I tried merging the latest upstream version of pdf.js into our custom fork and it caused some issues that I am going to have to investigate.

This may take a bit of time so I am not going to fix this until after the upcoming 8.0 release, as that has top priority. I will keep you posted on this issue.

Thank you!
Logan

Hi Logan,

Document doesn’t loading in the VIEWER is the biggest issue for any customer.
So my question is, Whether 8.0 release will resolve this issue ?
If not then, This issue should be considered on top priority rather than any new release.
If yes then, In how many hours or days or weeks, 8.0 will be released ?

Because this issue cannot be keep open since long, hope you will understand my point.
Please revert when you gets online.

Warm Regards

Hi there,

As stated on our website, issues related to the PDF.js core are not technically supported by PDF.js Express, which is why I am making this a lower priority. It is also a lower priority because it only effects a small % of documents.

I will try a bit more today to see if I can find an easy fix, but if not then this will not be fixed in the initial 8.0 release but will be fixed in 8.0.1.

We plan on releasing 8.0 early next week.

Thanks!
Logan

Turns out I spoke too soon and I happened to stumble upon a fix. Chrome / firefox added an at() function on arrays which broke some logic inside the pdf.js library.

I will push version 7.3.8 out today.

Thank you!

Correct, it fixes that warning and renders the PDF properly.

if you want, you can send me the document you are testing with and I can test it out before I release just as a sanity check.

That’s great… PFA of the same.

Please let me know if that works for you or not.

Could you please confirm the same document on Internet Explorer and Safari as well?

Hey,

Document works in Safari FF and Chrome - we do not officially support IE11 but it should work there as well too.

Will push patch after code review.

Thanks!

Thanks for the update, please let me know here, as soon as you push new release, as integration at myside with testing on the live site, will take some efforts.

Things are working with Viewer now.
However on the separate note, I am facing an issues while loading the documents on Safari and IE-11, and that could be due to my code ECMA script transpile issues, however I am not sure.

Could you please guide me on the same? that would be big help and truely apreciated…!!

Hi Logan,

Can you please revert on my above message?

Hi,

Express is heavily tested inside both IE11 and Safari, so the issue must be coming from your end.

Unfortunately I cannot be of help here unless you can prove that the issue is coming from inside PDF.js Express.

If you do find an issue with Express, please open a new bug report.

Thanks!
