Extension engine bug: app.project.importFiles doesn't work as supposed to in Beta

[Alexander from MisterHorse.com]

Hello, 

1. Version of tha app: Premiere Pro 22.4.0.30 (probably it started happening in a few previous builds too)

2. Tested on Mac mini (M1, 2020). OS version 12.2.1 (Monterey)

3. We've encountered a bug that might break a lot of extensions when using "app.project.importFiles" api call. I am attaching a video, sample projects and a script example. Calling this API to import a .prproj results in error. 

The gist of the call is:

var path = '/Users/USERNAME/folder/toImport.prproj';

if (path){
    app.project.importFiles(
        [path],
        true, // suppressUI
        app.project.rootItem,
        false // importAsStills
    );
}

The root issue seems to be the "suppressUI" parameter which defaulted to "import everything" before.

Thank you for looking into this :-).

Annoying! 

We're tracking this as DVAPR-4237770, "app.project.importFiles() FAILS for .prproj files, in 22.4; works fine in 22.3".

Thanks for reporting this, Alexander! 

I've put you in touch with our API wizard and hope to have some good news on a fix soon. 

Thanks,
