Hi @kurokochin, thanks for contacting us about this issue.

The traceback does not appear to hit the Django Azure Storage library, despite the fact that it does hit Azure in the process of working with the storage. This can be confirmed by looking for azure_storage in the traceback, which is the Python package name. This might be because you are vendoring Django Azure Storage so you could make changes to it. In that case, there isn't a ton we can help with, since we don't have access to the vendored files, and any changes that were made may have been the cause of the issue.

If you are able to reproduce this issue when using the latest version of Django Azure Storage, it would be helpful if we could get a list of steps which need to be taken in order to consistently reproduce this error. Since we aren't using Heroku, it's impossible for us to reproduce any Heroku-specific issues, but we may be able to track down the cause.

Also, the traceback that you provided either appears to be incomplete or in the wrong order.
