Filesaver.js: Latest version of Chrome iOS opens blank "about:" page

[bsteeves]

Unable to download a file correctly in the latest version of Chrome iOS (71.0.3578.77). Instead of previewing the file a blank "about:" screen is shown. Works correctly on Safari and Firefox.

iOS version 12.1

Can reproduce the behaviour on the demo site: https://eligrey.com/demos/FileSaver.js/

...the demo is quite old

It's not just the demo, I'm seeing it on my website that uses the latest version of FileSaver. Same behaviour as the demo site.

I have the same issue in chrome IOS only. It works on Chrome Desktop. I also works on IOS with safari, Firefox or Opera.

Has anyone had any luck debugging this?

I made some progress here. Seems typeof FileReader === 'function' sometimes and Chrome IOS will not open objectUrls or data urls.

The only thing I have somewhat working was changing always changing to data:attachment/file; and not doing a popup, just doing location = url. This causes Chrome IOS to prompt the user to download the file, but the catch is the file is just named document and with no pdf extension (in this case) it's not usable :(

@scottkidder I don't know if I get you correctly, but assuming that you have working solution for this issue, could you share some code example?

This issue appeared on 2018-12-4 with Chrome IOS version 71.0.3578 and is resolved after updating to the latest version (72.0.3626 - 2019-1-29). Could someone else update Chrome from the App Store and confirm?

@jmichel84 Wow thanks for the heads up. Are you aware of any issue and/or release notes that mention this issue?

[scottkidder]

I can confirm this is fixed with latest Chrome

[bsteeves]

Same. File download is working as expected in the latest version of Chrome

I have reproed this with Chrome 87.0.4280.77 on an iPhone XR running iOS 14.3-beta. When I use code-as, instead of previewing the file a blank "about:" screen is shown. When I try without the pop-up, and with and without always changing to data:attachment/file;, Chrome iOS prompts to download the file, but the the file is just named document with no extension. I am passing a Blob with type image/jpeg.

It is formatted correctly and I'm able to download it using Safari iOS. This is an old issue, so I can file a new issue to discuss this, if we'd like.
