400 Error - Path root is not supported for sandbox app
I'm new to the dropbox API and getting an error I can't find a clear explanation for when building a Make.com automation.
[400] Error in call to API function "files/upload_session/start": Path root is not supported for sandbox app
Can anyone help me understand the nature of this error, and where I go to resolve it? I have a Scoped App with all the Files & Folders permissions active, and the make.com redirect in place.

This error is indicating that the app is registered for the "app folder" access type but it is setting the 'Dropbox-API-Path-Root' header when calling the Dropbox API.
Apps with the app folder access type can't use the the 'Dropbox-API-Path-Root' header, because they are always automatically rooted to their app folder.
To resolve this error, you should either not set that header, or if you do need to access content outside the app folder, register a new app with full Dropbox access instead.
