Objective C batchUploadFiles gives error: "missing required field 'session_id'" or "Garbage at end."
Hi,
I am getting the error

- 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!

You were right, it was the completetion code being put into the progressblock. Its now working. Many thanks.
I've updated the new code
I'm actually receiving the same error, but I've got the correct code in the response block (I think). It doesn't seem to happen on the first batch upload call during a run, but the second upload attempt seems to fail pretty consistently. Here's my code, if it helps.
[self.fileRoutes batchUploadFiles:filesToUpload queue:self.fileUploadQueue progressBlock:^(int64_t uploaded, int64_t uploadedTotal, int64_t expectedToUploadTotal) { if (fileSize.intValue > 0) { float progress = (float) uploadedTotal / fileSize.longLongValue; photo.uploadProgress = progress; } } responseBlock:^(NSDictionary<NSURL *, DBFILESUploadSessionFinishBatchResultEntry *> *fileUrlsToBatchResultEntries, DBASYNCPollError *finishBatchRouteError, DBRequestError *finishBatchRequestError, NSDictionary<NSURL *, DBRequestError *> *fileUrlsToRequestErrors) { DBFILESUploadSessionFinishBatchResultEntry *result = fileUrlsToBatchResultEntries[srcPath]; if (result.isSuccess) { [self uploadedFile:destPath from:srcPath.absoluteString metadata:result.success]; } else { NSMutableDictionary *userInfo = [[NSMutableDictionary new] autorelease]; userInfo[@"path"] = srcPath.absoluteString; if (fileUrlsToRequestErrors) { NSMutableDictionary<NSURL *, NSString *> *errors = [[NSMutableDictionary new] autorelease]; for (NSURL *key in fileUrlsToRequestErrors.allKeys) { errors[key] = fileUrlsToRequestErrors[key].errorContent; } userInfo[@"fileErrors"] = errors; } if (finishBatchRouteError) { userInfo[@"routeError"] = finishBatchRouteError.description; } if (finishBatchRequestError) { userInfo[@"requestError"] = finishBatchRequestError.errorContent; } // TODO Handle conflicts here if (result.failure.isPath){ if (result.failure.path.isConflict) { // TODO Handle This DLog(@"Conflicting filename: %@, %@", photo.filename, result.failure.path.conflict) } } NSError *err = [NSError errorWithDomain:@"my.app" code:0 userInfo:userInfo]; [self uploadFileFailedWithError:err]; } }];
