If I add a file to a new group's discussion, the file appears to upload but is not downloadable. When I look at the S3 bucket, in images/files/discussions, the new group's subdirectory has not been created and the file has not been uploaded.

I have verified that the cron job is executing, with the results:
<?xml version="1.0" encoding="UTF-8" ?><messages><message>Could not convert video</message><message>No temporary videos to delete.</message><message>0 files transferred.</message><message>0 video file(s) transferred</message><message>No avatars or cover of users needed to be transferred</message><message>No avatars or cover of groups needed to be transferred</message><message>Removed Pending Invitation for Past Event</message><message>0 files transferred. to s3</message></messages>

so it thinks there are no files to transfer.

Hi David,
