Unable to do a manual backup in snapshot

Hello Team-

I have a member that is unable to create a full backup with snapshot. He continues to get an error

Aw shucks, something went wrong :slight_frown: Instead of the beautiful response we expected, we got this:
Other kind of backup error

Cpanel access credentials are within the transcript, I enabled the debug.log tried to backup again and recovered the data. It only contains one entry:

[25-Apr-2017 18:55:44 UTC] PHP Notice: Trying to get property of non-object in /home/facadenv/public_html/wp-includes/class-wp-query.php on line 3884

Take Care,
