Development npm scripts now also listen for debuggers:
- Port 9229 for the bot
- Port 9239 for the api
Via Knub 28, PluginErrors are no longer used in development, which
helps with call stacks in debuggers (see Knub changelog).
Unhandled promise rejections are now treated as exceptions via nodejs
flag --unhandled-rejections=strict, which allows catching them with
a debugger.
The internal "error-tolerant" error handler is now only used in
production; in development, all unhandled errors cause the bot to
crash and are easily catchable by debuggers.
