Fail to get a file via curl

Soooo.... this has been driving me nuts for the past day or two. I am sure I am missing something obvious, but I have no other paths forward. So here goes. I have created an app with access to an APP FOLDER. I uploaded a few test files to the folder via GUI. I can list the folder contents via curl using the token I created. When I try to get a file, using the file id from the list_folder endpoint, I get a not found error. Code bellow. Please help!!!

 

curl -X POST https://api.dropboxapi.com/2/files/list_folder \
    --header "Authorization: Bearer <TOKEN>" \
    --header "Content-Type: application/json" \
    --data "{\"path\": \"\"}"

 

...Returns JSON with /App/FOLDER content... 

 

curl -X POST https://api.dropboxapi.com/2/file_requests/get  \
    --header "Authorization: Bearer <TOKEN>" \
    --header "Content-Type: application/json" \
    --data "{\"id\":\"<ID>\"}"

 

Returns: 

{"error_summary": "not_found/...", "error": {".tag": "not_found"}}

???? 

 

 

Thank you!
