Certificate Issue using put_file?

Question

Hi guys, we have an app that was working fine yesterday, but now when we use the client.put_file method we're getting a certificate verification error. Stack trace below -- any ideas please? I've rechecked our app key and secret and all looks correct. As i say, everything was fine yesterday. What a difference a day makes... ;)

File "/home/clicadmin/CLIC_Deployment_Scripts/build_utils/mis_manager.py", line 97, in do_put
self.api_client.put_file(self.current_path + "/" + to_path, from_file, overwrite=True)

Hi Dave, it sounds like you're using an old version of the API v1 Python SDK, with an outdated certificate file.

We reached out to developers using old SDKs like this last year to warn of this change, but it sounds like that email didn't make it to you unfortunately.

In any case, you should be able to fix this by just upgrading the version of the Python SDK you're using (to get the current certificate file). E.g., if you're using pip, that would a matter of running:

pip install dropbox --upgrade

Also, unrelated, I should note that based on your stack trace, it looks like you're still using API v1, which is itself deprecated. You should move to API v2 when you can. There's functionality for both API v1 and API v2 in the latest version of the Python SDK. You can find instructions on using API v2 functionality in the latest version of the Python SDK readme on GitHub.
