Hello @velazquezsheldon

In App Platform, the local filesystem on the host instances running App Platform containers is ephemeral. When deployments happen or containers are replaced the local disk storage will be LOST and not recoverable. To use App Platform you must re-implement or reconfigure your app to use other forms of persistent storage such as Spaces (where you can save your images). The local disk should only be used as temporary storage.

You can take look at our sample Node.js app and its limitations at Link

Alternatively, you can choose to deploy your app in Droplet instead of App Platform. You can refer to the tutorial link below for more information:
