Thanks for the report! It looks like the SDK is receiving invalid JSON for some reason. I'm not aware of anything that should be causing that right now, and I can't seem to reproduce this myself, so we'll need to look into it specifically for you.

Would you be able to print out the problematic response body? That may help show what the issue is. For instance, you could reproduce the call outside the SDK by calling /2/team_log/get_events/continue by plugging in your access token and the relevant cursor. Please feel free to open an API ticket if you'd prefer to share privately. Either way though, please don't share your access token.

Hi,

as a follow up, I opened a ticket https://dropbox.zendesk.com/hc/en-us/requests/10673253 and I believe that the error is parsing "file_locking_lock_status_changed" event types.

Greg-DB

Thanks! That's very helpful. We have your ticket and are working on reproducing and investigating this issue based on that information. We'll follow up with you once we have an update on that.

Hey,

I have the same issue, do you have any status update fro this ticket?

Greg-DB

@guymayor Thanks for checking in. We were able to reproduce this issue internally. This is now open with engineering, but I don't have an update on it yet. I'll follow up here once I do.

This should be working properly in the latest version of the SDK. Please give that a try and let us know if there are still any issues with that. Thanks!
