Python SDK constant errors
Trying to make a small app that will read a pair of files from a dropbox folder and compile a small database from them. Just getting started, following the sample but I keep getting errors of different kinds.
I'm using virtualenv and have only installed dropbox and its dependencies using
pip install dropbox
This is my pip freeze:
appdirs==1.4.3 certifi==2017.4.17 chardet==3.0.3 dropbox==7.3.1 idna==2.5 packaging==16.8 pyparsing==2.2.0 requests==2.16.5 six==1.10.0 urllib3==1.21.1
Trying to run the files_list_folder example, I first had an issue that any folder name would not pass some regex validation. Even a name as simple as 'testFolder' would fail.
Traceback (most recent call last):
File "process-dropbox.py", line 7, in <module>

I decided to try an empty name (supposedly for the root directory) and that seems to pass the validation, but then it throws this error.

I also tried users_get_current_account and got the same error.
Not sure where to go from here. This feels like the dependencies are perhaps not the right versions or something. I am not sure where to go from here.
Thanks in advance for any help.
- It looks like the ValueError issue is fixed in requests v2.17.1, so please update to that and let me know if you're still seeing any issues.

Thanks for writing in. Note that the first error is because non-root paths should start with a '/'. So, your path there should be "/testFolder", not "testFolder". The root path is identified by the empty path "".
The second error did start occurring with recent changes to the requests dependency. We're looking into that. As a workaround though, you can downgrade to requests v2.15.1.Thanks! By downgrading I have managed to run some of the API functions, but now I have another problem.
The app I started using has App Folder permissions (set to 'testFolder') and from what I can tell, the path used for endpoints is relative to that folder. So, if I want to list the contents of 'testFolder' I actually pass an empty path, correct?
Now, the issue is that I get an empty 'entries' array when I try to list the contents of 'testFolder' even though there is a file there.
I tested listing the contents of 'testFolder' with an app with 'Full Dropbox' permissions and it does list the file.Any idea what could be the issue?
- Greg-DBThat's correct, if your app has the "app folder" permission, everything your app does or "sees" is relative to the app folder itself. You would use "" to refer to the app folder itself, since it's your app's root, or "/subfolder", etc. to refer to something inside your app folder.
From your first paragraph, it sounds like "testFolder" is your app folder itself, so to list its contents you would use a path parameter of "". In your second paragraph, it sounds like you may be trying to specify "testFolder", which wouldn't be necessary. If you're still not seeing the expected results, please share the code and output.
Also, note that the full Dropbox version wouldn't be looking at the same files if you pass the same path string. I.e., using the path "/testFolder" would list the following folders, as seen on the Dropbox web site, for the respective permissions:
- full Dropbox: /testFolder
- app folder: /Apps/<app folder name>/testFolder
