Could not write file "mwstore://AmazonS3/local-public/...

I recently started getting these errors and I am struggling to figure out why.

Nothing has changed in my AWS configuration. The IAM configuration is still good and all of the bucket settings have not changed.

I am on PHP 7.4, MediaWiki 1.35, Extension:AWS 0.11.1. This hasn't really changed either.

I did recently update my composer dependencies. Per the MediaWiki documentation I removed my composer.lock file and ran composer install

Files are still being read from the bucket correctly.

Does anyone have troubleshooting suggests or know what the issue is?

I verified that the AWS credentials I am using are still working correctly. I also tried using the latest code from the extension's repo.

To be clear, this was working just fine a few weeks ago and the only thing that has changed since then was that I updated the composer dependencies and I enabled the VisualEditor functionality.

Here is the error I am seeing in the debug logs (some information obfuscated):

And here are the versions Composer is using for the extension's dependencies:

  - Locking aws/aws-sdk-php (3.209.17)
  - Locking composer/installers (v1.12.0)

The issue is that my Wiki and bucket are private and I did not have $wgFileBackends['s3']['privateWiki'] = true; in my local settings. I am still not sure yet how this was working before and then stopped but... it is working now.

Thanks to Edward for helping me figure it out on GitHub.
