Pdf.js: "The provided value 'moz-chunked-arraybuffer' is not a valid enum value... "

Created on 4 Aug 2015  ยท  27Comments  ยท  Source: mozilla/pdf.js

When I use PDF.js open a chinese document in chrome, part of contents in some pages are missed. the console tells "The provided value 'moz-chunked-arraybuffer' is not a valid enum value of interface XMLHttpRequestResponseType."(webL10n/l10n.js,L829) and "The provided value 'moz-chunked-arraybuffer' is not a valid enum value of interface XMLHttpRequestResponseType."(pdf.worker.js,L1649), the chrome version is 43.0.2357.132.

Working version of @Rob--W's suggestion which prevents the warning.

pdf.worker.js - line: 8769

- var supportsMozChunked = (function supportsMozChunkedClosure() {
+ var supportsMozChunked = !(typeof navigator !== 'undefined' && /Chrome/.test(navigator.userAgent)) && (function supportsMozChunkedClosure() {

This should have been fixed by #5531 are you using a pdf.js newer than that?

I can conform the moz-chunked-arraybuffer warning is happening on the demo viewer on Chrome 44.0.2403.125 OS X 10.10.4

pdf.worker.js:1649 The provided value 'moz-chunked-arraybuffer' is not a valid enum value of type XMLHttpRequestResponseType.

However it is merely a warning Chrome displays during feature detection and doesn't indicate any sort of error.

5531 only remove feature detection for Chrome and Firefox build but not generic viewer so it doesn't really solve the warning for generic viewer.

@CodingFabian the feature detection bit still occurs if MINIFIED or GENERIC build targets are used:

Wait, why this is closed? I'm still getting the warning

The provided value 'moz-chunked-arraybuffer' is not a valid enum value of type XMLHttpRequestResponseType.

on Chrome 44.0.2403.130 (64-bit) with pdf.js 1.1.377.

Waity, why this is closed?

See #5531

I'm using pdf.js-dist 1.1.377 and still get this warning. I'll debug this in a bit.

You will get the warning but only once -- it will feature test ability to load data in chunks.

I understand. I guess it's all working as expected then, and everyone can ignore the warning. It's really quite funny though that there should be one.

There seems to be a lot to discuss, I reopen it. Sorry about what I've done.

@qingzhengzhuma I think it's fine to close this issue. We still have a warning here (which I would consider an issue indeed), but we're looking at https://github.com/mozilla/pdf.js/issues/6126#issuecomment-130462101 as a possible fix, we can discuss everything over there.

Any updates on this warning? im still getting it...

@lenichols This was fixed in #5531. Which version of PDF.js are you using?

I am using Pre-built v1.3.91 and also getting the warning
I also can see the warning on chrome on the demo page http://mozilla.github.io/pdf.js/web/viewer.html

Ah, that is right. There is no warning in the Chrome extension, because that code is removed during the build. But it is present in a generic build because it is not known upfront Firefox, or some other browser is used. Just ignore that warning.

I'm using v1.4.124 of pdf-dist from npm, and the warning The provided value 'moz-chunked-arraybuffer' is not a valid enum value of type XMLHttpRequestResponseType. appears in Chrome console every time I render a page. I'm still in the middle of getting my document viewer to work, but I don't think it's related to any problems. I'm just here to whine that it's an annoying message. :weary:

getting same warning with v1.4.131.....

@timvandermeij This message seems to bother a lot of people. Should we add a simple conditional check for Chrome (e.g. !window.chrome && ...)?

@Rob--W I agree that the message is not ideal. We want to avoid browser-specific code in the src folder as much as possible, but if there is no other way then I guess we have to go for it. You can always submit a PR and see how other developers think about this.

Working version of @Rob--W's suggestion which prevents the warning.

I'm still getting this warning... Using chrome 53 and latest pdf.js beta

Still getting this warning on Chrome v55.0.2883.87
