Need help with Android adaptive icons

[emv33]

I'm becoming desperate trying to use an adaptive icon for my app. I used this tutorial to generate my icons. I copied the entire res folder into my cordova app in res/android. I currently have this

<platform name="android">
    <resource-file src="res/android/values/colors.xml" target="/app/src/main/res/values/cdv-colors.xml" />

    <icon background="@color/white" density="mdpi" foreground="res/android/mipmap-mdpi/ic_launcher_foreground.webp" src="res/android/mipmap-mdpi/ic_launcher.webp"/>
    <icon background="@color/white" density="hdpi" foreground="res/android/mipmap-hdpi/ic_launcher_foreground.webp" src="res/android/mipmap-hdpi/ic_launcher.webp"/>
    <icon background="@color/white" density="xhdpi" foreground="res/android/mipmap-xhdpi/ic_launcher_foreground.webp" src="res/android/mipmap-xhdpi/ic_launcher.webp" />
    <icon background="@color/white" density="xxhdpi" foreground="res/android/mipmap-xxhdpi/ic_launcher_foreground.webp" src="res/android/mipmap-xxhdpi/ic_launcher.webp" />
    <icon background="@color/white" density="xxxhdpi" foreground="res/android/mipmap-xxxhdpi/ic_launcher_foreground.webp" src="res/android/mipmap-xxxhdpi/ic_launcher.webp" />
</platform>

(I changed colors.xml to cdv-colors.xml because of this bug in the documentation that is still there)

I get the following error:

This is my file tree in res/android:

(I deleted the contents of drawable because it contained default icons. Also, ic_play is a notification icon that is unrelated to this issue)

Alright solved... turns out the issue is that cordova does not support webp icons. I didn't even convert them, just renamed webp to png and it works fine now. Thanks to anybody reading though! :P
