In my case I had this issue because I was using the wrong content type to post the data.
This endpoint is actually very confusing because unlike all the other endpoints (which accept application/json) it accepts application/x-www-form-urlencoded, and if you use the wrong format it will respond with this absurd error message "No auth function" even though there can't be an auth token at that point.In my tests other mistakes in the data format (like missing client ID or secret) also resulted in this error .
From the doc it's unclear whether client ID and secret are required or not (I have no idea what "If credentials are passed in
POSTparameters" means in this context) but they seem to be required anyway.So in my case I eventually got it working using this kind of request:
curl -v -F 'client_id=REMOVED' -F 'client_secret=REMOVED' -F 'code=REMOVED' -F 'grant_type=authorization_code' https://api.dropboxapi.com/oauth2/token
