I can see the error is my icon.
I can see its referring to alpha channel.
But there is only alpha channel on my dark icon and tinted icon.
There is no alpha channel on the default icon.

Im lost in what the error could be.
there is no problem uploading manually throught xcode.
There is no problem running the fastlane command locally on my own macbook.

But as soon as i use azure devops pipeline, i get this error.
Any idea?
