BUG - Data loss through dropbox

garvan walshe 3 years ago in iPad updated by ryanbeard82 2 weeks ago 7

1. I started a new document, to be saved on Dropbox while offline. finished it. closed my ipad.

2. Opened my ipad at work, where it connected to my wifi

3. It then deleted the contents of the document saying “couldn’t communicate with a helper application.”

Result: I lost my column which has to be filed in two hours. 

I just had the exact same experience using OneDrive. Is there a local cache I can access to recover my data?

How exactly did you create the new file and where did you save it? Did you use the "Create External File" command while offline?

(I don't use OneDrive myself, but I heard a few times that the OneDrive file provider is not very reliable.)

That’s correct. I used the “Create External File” command. Entered a titled and file extension (.txt), then click “Choose Location” and selected a directory on OneDrive and clicked “Move”. I didn’t receive any errors when creating the file, but I’m getting the same “helper application” error now when trying to retrace my steps. I def was not offline - have been working from around the house on stable Wi-Fi.

Here's the full log text from the error:

Thanks for the logs, I'll try to reproduce it.

I can reproduce the issue when trying to use "Create External File" with OneDrive.

This looks like a bug in the OneDrive file provider that is out of my control. 


I tested it successfully with Dropbox, iCloud Drive, "On my iPad" and Working Copy - only OneDrive seems to have this problem.

Appreciate the help and confirmation.
