Inventory file not accessible in "choose an inventory file"

Hello,
I use AWX 17.0.1
I want to create an inventory with a “source from a project”. When I add a file to a new directory I don’t see it in “choose an inventory file”.
I checked on the awx-task pod and my file is present in / var / lib / awx / projects.
How should we do it? Are there any naming rules to follow?

Thank you for your help
