why this massage

I'm a Windows user, but this sounds like a Mac disc permissions issue we've seen a lot here. Make sure you've granted full disk access to InDesign by following the instructions at https://community.adobe.com/t5/photoshop-ecosystem-discussions/quick-tips-learn-how-to-give-full-disk-access-to-photoshop-on-macos/m-p/12889716

Just substitute InDesign where it says Photoshop (I'd do all the Adobe apps while you're doing it, myself).

Hi @Omar Ghazalx ,

will it work if the target of the package is your Desktop folder?

If yes you could move the package to the intended folder wherever that is.

Hi @Omar Ghazalx ,

could be that InDesign has not sufficient rights to write to the target directory or folder.

Or it could be that the overall paths of some of the packaged items will be too long in your system; something that can happen on Windows machines easily.

So: try to package your InDesign document to the Desktop folder.

That should work.
