After migrating to this latest version, we are seeing empty message is being passed and it looks like the platform_message is never getting set. Please advise.

Which network (Slack, Facebook, etc) is your bot using?

platform_message is populated by format middleware which is specific to network:

We migrated from 0.5.4 and using a bot that extended from CoreBot ../botkit/lib/CoreBot.js

All Bots extends CoreBot, do you use builtin Bot or a custom made one?

If you have implemented your own custom Bot, the you have to add format middleware to it.

Yes, we have a custom bot. Thanks for the clarification.
