1. The file is indeed gone. Our permissions have not changed and everything is appropriate.
2. The checkpoint locations have not changed and are still accessible with the proper permissions as I mentioned in item 1.
3. Clearing the existing checkpoint locations is the only thing that works. This is not an acceptable long-term strategy however, because that means each of these pipelines will need to be re-processed and I'll be forever chasing my tail and deleting checkpoints with issues.
4. I'm already managing the checkpoint locations manually in S3.
5. I haven't manipulated the state provider configuration. It's all the default values.
