Folder Listener keeps creating submissions from the same files

Issue

By design, the Folder Listener will retrieve submission files from the specified target folder and then delete the original files. However, in some cases, the application keeps creating submissions from the same files in the target folder, resulting in duplicate submissions.

Affected versions

All versions

Affected configurations

All configurations

Cause

The application does not have Write permissions for the target folder, so it cannot delete the submission files as they’re retrieved. As a result, the same files are retrieved every time the Folder Listener checks the target folder for new data.

Solution / Workaround

Check the application’s Write permissions for the target folder, and add them if they are not already set. Then, the application can delete the original files for the submissions after the submissions are created.
