Receiving errors with installation of v2 Dropbox Business App for Splunk

[mattalshab]

Hi,
Installed v2 of the Dropbox app on our server running Splunk 7.1.3. I get a bunch of python errors and no data gets added to the index. I can use cURL to pull the events from the CLI so communication/authentication isn't an issue. We are currently running Python 2.7.5 on this server. I'm wondering if the app supports Python 2.7.5 or if I need to upgrade to Python 3.7

Can anyone confirm which version(s) of Python the dropbox for business app supports??

Just wanted to note that I am seeing 404 errors from splunkd api. Not sure if this could be root cause or the python errors. I should note that there are a bunch of other splunkd api endpoints that do resolve properly (status=202). Have no idea where to go from here. Any thoughts would be appreciated.
