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.

All comments

Greg-DB

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.

RCR

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-DB

That'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

Greg-DB

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.

RCR

Sorry I wasn't clear. Let me try again.

I have a folder called 'testFolder' and two apps. The folder itself has 1 PDF file.

For the app with access to a single folder, (set to 'testFolder' in the app settings), the following produces an empty list of entries:

for entry in dbx.files_list_folder('').entries:
    print(entry.name)

Now, for the app with full access, the following produces a list with the one entry for the PDF file:

for entry in dbx.files_list_folder('/Apps/testFolder').entries:
    print(entry.name)

These two operations are supposed to be accessing the same folder, are they not?

Thank you for your help so far

Greg-DB

Thanks for clarifying. Yes, those two should give you the same listing.

Make sure both apps are linked to the same account though. You can use users_get_current_account to check that.

If you're still getting unexpected results, feel free to open a ticket with the specific code and output from the affected account and we'll be happy to look into it specifically for you:

Well, this is curious. I have firgured it out, but I'm not sure if this is a glitch or not.

So, the original name of the folder for the app was the name of the App (something like App-Test-Name), but, like I said, I changed it in the settings to 'testFolder'.

I then created a folder with that name within the Apps folder. Right beside the original App-Test-Name folder.

I tested now (by adding a different file to App-Test-Name), and the single-folder app is actually listing the contents of the 'App-Test-Name' folder instead of 'testFolder'.

Something seems off here...

Greg-DB

Manually creating a folder won't connect it to your app. The app folder is a special app folder automatically created for the app when the app is linked to the user's account.

Also, if you change the app folder name setting for an app, it won't change the name of any app folders already created in already linked user accounts.

So, it sounds like this is working as expected, since the existing app folder was "App-Test-Name", and "testFolder" was just the normal folder you created after the fact.

RCR

I see...

But then, what is the purpose of the 'App folder name' setting in the App dashboard?

I assumed that it would change the name of the connected folder after I changed the setting, but when it didn't, that's when I created the other folder.

Greg-DB

The app folder name setting would be used when setting the name of new app folders when more users link to your app. Changing it won't change the name of existing app folders though.

I have the same problem. But I updated my requests to v2.18.4.
when I run:
dbx.users_get_current_account()

It shows error message:

ValueError: Timeout value connect was Timeout(connect=30, read=30, total=None), but it must be an int, float or None.

Greg-DB

If you're still seeing ValueError, make sure you're on the latest version of the requests library, and double check that that latest version is actually getting used in the Python environment that you're running in.

Additionally, we received a report that this issue can persist if you're using Python 3.6.1, and that upgrading to 3.6.5 can fix that.
