Increased invocation failures for Hobby Team functions

This incident has been resolved.

We have deployed a fix and are continuing to monitor. Function invocations for new Hobby Team deployments should no longer fail. If you are still experiencing function invocation errors, redeploy or rollback to a previous deployment.

We have identified the source of errors and are implementing a fix.

There are elevated rates of invocation failures for Hobby Team functions in new deployments. Existing deployments are unaffected. We are investigating. Mitigation is possible by rolling back to a previous deployment.
