App Store Connect error IMAGE_TOOL_FAILURE when uploading app screenshots

Question

I am getting this annoying error as I am trying to upload screenshots of my app before submission.

• The error appears after I upload images for any screen size, and when I try to upload more images for another size.
• It appears in the Version Information screen but also in the media manager.
• It does not matter how long I wait between uploads and does the same with Safari and Firefox.

Has anyone of you seen this and found a workaround?

Thanks

I run into this today, too. 3 out of 7 of my screenshots failed. Consistently and always the same three.

I tried renaming the file and exporting it as a PNG without the alpha channel, but it didn't work.

What worked was going out of the Media Manager page re-uploading the "invalid" screenshots individually, leaving the Media Manager page before attempting a new upload.

When I went back to the home page for the app, the screenshot I uploaded didn't show the IMAGE_TOOL_FAILURE error. I repeated the process for the other two, again by uploading only one via Media Manager and then going out of that page, and it worked.
