shared app directory, exists but inaccessible to my app

Yes, now I understand. Just tried it and it worked perfectly; will modify my app, this is a far better solution than creating links!! I find 

mymac:acme1066 localuser$ pwd

/Users/localuser/Dropbox/Apps/acme1066

I created Monday, Tuesday, Wednesday etc within it and I list it with ..

curl -X POST https://api.dropboxapi.com/2/files/list_folder     --header "Authorization: Bearer <REDACTED>"     --header "Content-Type: application/json"     --data "{\"path\": \"\",\"recursive\": false,\"include_media_info\": false,\"include_deleted\": false,\"include_has_explicit_shared_members\": false}"

{"entries": [{".tag": "file", "name": "Monday", "path_lower": "/monday", "path_display": "/Monday", "id": "id:-jRneIVvgyAAAAAAAAAAAQ", "client_modified": "2016-06-21T05:12:51Z", "server_modified": "2016-06-21T05:12:56Z", "rev": "14a2437b4", "size": 0}, {".tag": "file", "name": "Tuesday", "path_lower": "/tuesday", "path_display": "/Tuesday", "id": "id:L1y7LIaRepAAAAAAAAAAAQ", "client_modified": "2016-06-21T05:12:56Z", "server_modified": "2016-06-21T05:13:02Z", "rev": "24a2437b4", "size": 0}, {".tag": "file", "name": "Friday", "path_lower": "/friday", "path_display": "/Friday", "id": "id:14SCeRsPtOAAAAAAAAAAAQ", "client_modified": "2016-06-21T05:13:11Z", "server_modified": "2016-06-21T05:13:16Z", "rev": "54a2437b4", "size": 0}, {".tag": "file", "name": "Wednesday", "path_lower": "/wednesday", "path_display": "/Wednesday", "id": "id:1VmOHG4gINAAAAAAAAAAAQ", "client_modified": "2016-06-21T05:13:00Z", "server_modified": "2016-06-21T05:13:06Z", "rev": "34a2437b4", "size": 0}, {".tag": "file", "name": "Thursday", "path_lower": "/thursday", "path_display": "/Thursday", "id": "id:_X1Hb6Ty6VAAAAAAAAAAAQ", "client_modified": "2016-06-21T05:13:06Z", "server_modified": "2016-06-21T05:13:12Z", "rev": "44a2437b4", "size": 0}], "cursor": "AAH6ZRqDays_h4zJR0z1EgLGtQzbKadBnTqOSd_O-sOp4I8gVBWLKvP4PInbvHxLhQrttjnS6NfHNVyP61piiIbf8Hvxi2K8QoW_T3ykuCjLwb9k6kuBpJ9_KpluePvypAY", "has_more": false}

And it works perfectly!!
