convert.leiapix.com - Unable to upload images

MetaMmodern commented 6 months ago

Browser / Version: Firefox for Android 124.0.0 Operating System: Android 13 Tested Another Browser: Yes Firefox

Problem type: Something else Description: Can't upload an image Steps to Reproduce:

Open the website, sign in.
Click "Upload" button.
Select any supported image (png/jpg)
Wait for the loading to start.

Expected behavior: uploading image works, loading shows up and animation is shown afterwards. Actual behavior: uploading doesn't even start and fails at 0%.

Notes:

tested on Firefox for Android v123.1.0, it works just fine there, so you can go try it out there to see how expected behavior looks like.
as engineer I can tell that under the hood image is being validated, processed, resized and converted using HTML canvas element. We saw it was failing on validation step, during debugging we disabled validation and it started failing on next, resizing step. So we tried to generate an objectURL generated from original uploaded File and put it on page with tag and it was showing a corrupted file. Something broke in image processing probably.
happens with any images.
doesn't happen in other browsers.
for some reason doesn't happen with random codepen examples that we tried finding on internet.

@sv-calin thank you. Just as a reminder: this is actually a fresh regression, so it should be not that hard to find the root cause of it. So if there's appropriate label for it please add it, cause I see you mentioned Chrome as non-repro, but I don't want this bug to be seen in shadow of chrome:)))
