My dropbox files get broken after a while

I'll be happy to help with any issues you're having with the Dropbox API, but I'll need some more information. Please reply with:

• the steps to reproduce the issue, including relevant code snippet(s), but don't include any access or refresh token(s)
• the full text of any error or unexpected output

Uploading a file to Dropbox and Getting the shared link:

Function to get the shared link

Internal Dropbox Client function to generate the file's shared link

And it works perfectly, the shared link works, but after a while (1-2 days) the files stored in dropbox starts to broken. I thought the issue was caused by the shared link's default expiration, but i dont think so: 

Thanks for following up with the additional information. So when you refer to the file being "broken", I see you're referring to the Dropbox web site being unable to preview the image.

The existence or expiration or a shared link shouldn't corrupt a file. If a shared link is no longer valid, the shared link page would no longer load at all; it wouldn't change the file data.

I suggest checking a few things:

• Are there any other clients or operations running on your Dropbox data that may be changing these files? You may want to check the event history.
• What is the size of the file when it is broken? Is it a different size than when you originally uploaded it?
• What data is actually in the broken file?
• If you download the broken file, are you able to view it as an image locally?

1.- There´s nothing about removed files activity.

2.- The file's size changes.

3.-

4.-

There's nothing.

1. The file wouldn't necessarily have been removed. It seems like it may be edited.

2. If the file size changed, it sounds like it was edited at some point. You can check the version history of the file.

3. It's unclear what you're showing in the last screenshot. Is that you attempting to view the file on the Dropbox web site or locally after you downloaded it from the Dropbox web site? It may be helpful to inspect the contents in a text or binary editor locally to see what is in the file.
