error in info.plist when validating app

I'm trying to implement the dynamic icon change, I made the settings in info.plist but when I go to validate I get this error message.

"Invalid Info.plist value. The value of the CFBundleIcons.CFBundleAlternateIcons Info.plist key is not valid. Learn more at https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html#//apple_ref/doc/uid/TP40009249-SW14."

, here is my info.plist

	<dict>
		<key>CFBundleAlternateIcons</key>
		<dict>
			<key>Icon2</key>

				<key>CFBundleIconFiles</key>
