Objective C batchUploadFiles gives error: "missing required field 'session_id'" or "Garbage at end."
Hi,
I am getting the error
DropboxBadInputError[{
ErrorContent = "Error in call to API function \"files/upload_session/finish_batch\": request body: entries.cursor: missing required field 'session_id'";
RequestId = 0af1f37eb6e9ebc3e7ea0695db52c593;
StatusCode = 400;
UserMessage = nil;
}];
And
"DropboxClientError[{\n NSError = \"Error Domain=NSCocoaErrorDomain Code=3840 \\\"Garbage at end.\\\" UserInfo={NSDebugDescription=Garbage at end.}\";
Search for the
[[DBClientsManager authorizedClient].filesRoutes batchUploadFiles:uploadFilesUrlsToCommitInfo queue:nil
inside the code.
I posted the entire method because I was worried that some part of the method maybe affecting the the batch upload.
The begin upload method works like this
1) it finds the photos that are present in the dropbox,
2) it compares it with photos present in the app,
3) then it deletes photos and other files that are in dropbox that are not present in the app or need to be deleted
4) Finally through batchupload it uploads all the photos that are not present into dropbox.
I really need help to fix this , been searching through the internet and trying different approaches but can't find an answer. Hopping someone can help
Update:(easier to implement code for anyone who wants to help)
Here is the entire code

- Thanks! This is very helpful. I'm able to reproduce this now. We're looking into it.
We have a rough idea of what's occurring, though not exactly why it's occurring yet. One thing that may be relevant though is that for some calls, you're using `setProgressBlock` and checking `if (totalBytesUploaded == totalBytesExpectedToUploaded` to see if the operation is complete. You should always use the response block (e.g., `setResponseBlock` for most calls, or passed as a parameter for `batchUploadFiles`) to know when the operation completed and then carry on with your next steps.
Please try making that change and let me know if it does or doesn't help. Thanks!

Thanks for the report! It looks like there's a good amount of code here, and I won't be able to run it, since it contains things from your app, like `WCPURLHelper`.
Can you isolate just the portion(s) of Dropbox related code that results in these issues so we can look into it? We'd first need to be able to reproduce the issue to investigate it.
Also, note that the latest version of the Objective-C SDK is 3.2.0. If you're not already on that version, please try upgrading to it first.Thanks Greg for helping.
I've edited the code to be easily tested, so you can lift it and put it in your app. All you need to do is:
1) In the documents directory of the iphone app make a photo and call it MainPhoto.db //yes change the extension to .db, this is to repiclicate the db file i transfer in the app
2) Next in the documents directory make a folder called photos, add about 20 or so pngs// you can just use cmd-d to duplicate one photo many times
3)Once you do that you should be able to run the method, this method will have "Garbage at end of file" then further use of this method will cause session_id errors
In addition, I've updated the dropbox api to 3.2 in the app, but the problems still occurs.

- Greg-DBThanks! That's very helpful. We'll look into it.
