Unable to upload file from my ios app.

[Mit Variance]

I am facing an issue when I upload a file from dropbox. It showing this message

"Bad Input: Error in call to API function "files/list_folder""

I can't see the file list also.

I have another same app using the same code in that app it's working perfectly and uploaded a file and see a list of my dropbox files.

But in another app, I am unable to see a list of dropbox files and I cannot upload files from dropbox.
