Random Error 500 when using batchUpload from ObjectiveDropboxOfficial

Hello,

I use the ObjectiveDropboxOfficial Framework and often get an error 500 when calling batchUploadFiles. It seems to be completely random for which file the batchUpload fails. I call batchUploadFiles for only one file at a time, because it has the convenience to chunk large files, etc. If it is important: the files to be uploaded in this case were all quite small (< 10kb).

 

requestIds:

 

DropboxInternalServerError[{
    ErrorContent = nil;
    RequestId = 1f5bee49483628499ea336ef74f9cb00;
    StatusCode = 500;
    UserMessage = nil;
}];

DropboxInternalServerError[{
    ErrorContent = nil;
    RequestId = 055da4b0e7b9fb9159da3d6308aee18e;
    StatusCode = 500;
    UserMessage = nil;
}];

DropboxInternalServerError[{
    ErrorContent = nil;
    RequestId = b911bde1db7f079fbc19af949df54074;
    StatusCode = 500;
    UserMessage = nil;
}];

Thanks a lot in advance!
