Answers.Text: Hi Brad, thanks for your time. Where would I go about looking at the Asset source settings? Where does $folder->sourceId come from? Is it a disconnect between the records in the "Assets" section and the data connecting to S3? Or is it a relationship inside the Craft database?

Answers.Text: Also, to further confuse the situation: HEROKU: Hangs on upload. DEV environment allows me to upload to S3, creating the asset record. Then on deletion, throws and error, deletes the assets record, but leaves the file on S3.

Answers.Text: So you're saying it worked before the 2.6 upgrade? I don't see anything in the release notes that changes any S3 functionality... wonder if something changed in your AWS credentials? Also possible you've ran out of disk space on your instance? (We've all been there.)

ThreadText: # Craft 2.6 Asset Upload 500 Error (on Heroku with Amazon S3)
  
  (Asked by: username_0 on 2016-10-04)
  
  I just upgraded a fully functional Craft website to Craft 2.6. The site is hosted on Heroku with assets uploading to S3. So all of that has been working really well for about 10 months. Now I can't upload any more assets. When I choose a file from my computer, the upload hangs.
  
  I get a console error:
  
  ```
  Failed to load resource: the server responded with a status of 500 (Internal Server Error)
  
  https://www.example.com/index.php?p=admin/actions/assets/uploadFile Failed to load resource: the server responded with a status of 500 (Internal Server Error)

  Line 707 of `craft/app/services/AssetsService.php` in the [latest](https://craftcms.com/changelog#build2945) Craft release references `$folder->sourceId`, which is where your error is occurring, so my guess is there is something incorrectly setup with your Asset source settings. I'd start by verifying those.
