The Dropbox SDK doesn't offer a way to enable more verbose output, such as for UploadAsync to offer more information about the operation. It's unclear exactly what's occurring here, or why you'd get a NullReferenceException on the variable being used as output, if that is what's happening. Can you print out the full stack trace for the exception? That may offer some insight.

    Hi Greg,

       The call stack just shows that the method is being called and is at line 305. See screenshot.

      Thanks, looking at that line then, is it possible DxClient itself is null? The screenshot is cut off, but I presume there aren't any other variables referenced that I can't see. The Locals pane shows stream and commitInfo as defined, but DxClient isn't shown.

        Hi Greg,

         

           DxClient is my global Dropbox client, and definitely not null, but in running my program again to get a screenshot of that for you I did find that it's not authorised! Not sure how that came to be, but I'll chase that down now, as that is probably why I'm getting this message (though not sure why I'm not getting some kind of message to indicate that). Will let you know how it goes.

         

        thanks,

          Donald.
