Page render promise throws errors and hangs reading process

See original GitHub issue

Hi,

the issue im working on is to render pdf’s with the size of 200MB and more, with not many pages, but full of content (less then 70 pages per doc).

One of pdf documents contain a page that is somehow corrupted. I don’t mind, cause all the rest displays well, but my reading process hangs when it comes to read this corrupted page.

What i’m doing is rendering pages to canvas using js promise like this:

var renderPromise = page.render(renderContext).promise;
renderPromise.then(function () {
    // render next page normally
})
.catch(function () {
    // handle exception situations
});

but it never enters catch block not then block… The process is stuck. Anyone can help me with this issue? Am i doing it wrong or pdf.js contain some bug and will never enter catch block?

Console log:

Unfortunately i cannot post this PDF public, because it may contain sensitive data, but i can show you more of my code that is responsible for displaying PDF pages

Not providing complete code and broken PDF adds additional and unnecessary complexity for a contributor to diagnose the problem (unless they have unlimited time to help with your project). In most cases such issues will stay unresolved and eventually closed as incomplete. Please add a link to you solution and/or provide sample PDF.

Closing as incomplete. Sorry, but link to the solution was not provided – code snippets and PDF are not helping to troubleshoot the issue.
