Unable to debug the action of sending email

[rjrodriguezalvarez97]

Hi, I've been trying to debug Mailtrain but I'm unable to do it. The child Sender process is unable to start while debugging but it starts properly during running. This is the output from running:

info Using local auth
Warning: connect.session() MemoryStore is not
designed for a production environment, as it will leak
memory, and will not scale past a single process.
info sql Database check completed
info Express WWW server listening on port 3000
verb UTC Updating timezone offsets
info POSTFIXBOUNCE Server listening on port 5699
info Service All services started

And this is the output from debugging:

/usr/bin/node --inspect-brk=42835 /home/ricardo/mailtrain/index.js
Debugger listening on ws://127.0.0.1:42835/ecaafed2-45de-4622-bcd3-c4f8d8a7bc93
For help see https://nodejs.org/en/docs/inspector
Debugger attached.

Starting inspector on 127.0.0.1:42835 failed: address already in use
info Service All services started
ERR! Child Sender process 8979 exited with 12

I think it might be caused because of child_process.fork() as explained here
nodejs/node#8495 (comment)

Any ideas or workaround?
Thanks.

Honestly, I thing it's close to impossible to debug a multi-process app with concurrently running co-routines. Just use log messages via console.out.
