Description

$ aurora beta-update status devcluster/www-data/prod/hello
Command failure:

TypeError: sequence item 0: expected string, NoneType found

The above happens due to this line [1] that attempts to match AuroraJobKey against thrift JobKey and results in a subsequent RPC call [2] failing with NPE.
