Using this.getLogger().log instead of console.log leaves no logs saved/printed.
Calling modify.getNotifier().notifyUser in slash command works without errors.

Message Result must exist for success Response objects seems to be from jsonrpc-lite, called from this line.

Apps Engine version: 1.45.0

Issue present in Rocket.Chat versions 6.10.x, 6.11.x, 6.12.0, 6.12.1.
In Rocket.Chat version 6.9.5 app works without errors.
