 * Not sure why this site is getting this error during backup since I have sites
   running [Stream plugin](https://wordpress.org/plugins/stream/) and Updraft without
   these errors. Any idea what may cause this? See log entries below:
 *     ```
       2092.365 (5) Resume backup (0a9f6db54c9b, 5): finish run
       2092.393 (5) There were errors in the uploads, so the 'resume' event is remaining scheduled

   > to be array, null given (line 192, wp-content/plugins/stream/classes/class-

 * Since the notices come from code from the Stream plugin (which can be determined
   by the path – what’s immediately after “wp-content/plugins” – you’d need to ask
   the Stream plugin people what it means and why it comes. To diagnose the problem
   with your uploads, I’d need to see the whole log (please post a link from pastebin.
   com or something like that – the wordpress.org forum moderators don’t like whole
   log files in forum posts).
 * Best wishes,
    David

 * Hey David,
 * Thanks. I did post in [Stream forum](https://wordpress.org/support/topic/stream-causes-e_warning-errors-during-updraft-backup?replies=1#post-7661422),
   waiting on a response from them.
 * Here’s the full log from one of the latest backup attempts:
