UpdateComputerEntity failing on first checkin

[missinformed]

I'm getting a 500 Internal Server Error when I try to connect a client for the first time to my simian instance. Here's the stacktrace from the GAE side:

Any ideas on what to try next?

For posterity, this fixed it:

gcloud app deploy app.yaml queue.yaml

The 'first' queue didn't exist, so it was failing.
