During the deploy this command is issued: 

$ SLS_DEBUG=* serverless deploy -v --stage cars --package sls-package-output --region ap-southeast-2

The

-v

is deprecated and a breaking change with v3 of serverless; released this week. Is that command part of the seed build image, or something I can fix myself?

Hey @John Mee, yeah it is a default command. We are in the middle of adding v3 support.
