Snap Palette to Front Window Plugin Action

Thank you for your quick answer @Tom. Even if I take your suggestion into account, the messages come. There must be something wrong with the applescript

It's confusing that the plugin works (video), but that these messages are always displayed and then also in apps that I don't use with this plugin. I also only targeted the used apps, but even there I get the error messages in all apps.

Here is a screenshot of my settings. Under KM 7 this worked perfectly.
