What this looks like is the artifact is taking a very, very long time to upload, so long that the credentials being used to upload it have expired. It looks like we managed to upload 2.8GB of it, and it also looks like it tracks with the overall corpus size...so presumably a large file is expected.

This is probably a freak occurence for two reasons:

• It looks like we were uploading at ~2MB/sec, which is quite slow AFAIK. I assume this is just GCP gremlins.
• This happened on docker-worker, which AFAIK doesn't refresh its credentials.

We probably can't do anything about the first thing. We just moved these tasks (and other docker-worker tasks) to generic-worker in #561), which does refresh its credentials. So, even if we hit slow uploads again it shouldn't cause a failure.

Unfortunately, I don't think there's anything tractable here other than switching to generic-worker :(
