When an error occurs, we get the immediate stack trace but not the entire stack trace. This often results in traces like:
```

This tells me nothing about where the operation originated from that resulted in the "Access Denied" error. Thus, my sad face surfaces.
I like my happy face and its probability of showing increases when I have messages that look like:

That is **clearly** (relatively speaking) a lack of S3 rights and I can fix that!
Switch to using a stream to read artifacts at upload, because it was
being read into a `const` that the AWS SDK had to then copy to a
bytearray that was wrapped in a TLSStream object, duplicating the
artifact several times.
