Get project file path in after effects by scripting

Hi
Why "app.project.file" is working with after effects 2023 but not for 2024 as it gives me null to a saved project??
Thanks

Make sure your project is saved, otherwise, it return:

app.project.file.fsName
// TypeError: null is not an object

i'm testing the same script on version 2023 and 2024 both of them has saved project is opened. script works for 2023 but not for 2024

Maybe you're using :

app.project.file

instead of:

app.project.file.fsName

Thank you so much; that helped me a lot.

with and without .fsName work, but it was my mistake. The project I opened in After Effects 2024 was originally created in After Effects 2023, so I noticed '(converted)' in the title bar. It hadn't been saved and had no file path, which caused the issue for me.
