What steps will reproduce the bug?

Checkout the branch chore/node/v8-fatal-error-reproduction of this repo. Then:

• npm run setup
• npm run start

You'll get:

[14:28:51.817] INFO (31321): Starting the service "bug"...
FATAL ERROR: v8::FromJust Maybe value is Nothing
----- Native stack trace -----

 1: 0x104427d74 node::OnFatalError(char const*, char const*) ...

How often does it reproduce? Is there a required condition?

Always.

If you add a comment on the 2nd call to pino (line 6), it doesn't occur.

What is the expected behavior? Why is that the expected behavior?

Node should handle the shutdown differently, instead of throwing.

What do you see instead?

A stack trace of the error from v8

Additional information

I'm available to provide further information if this can help to fix the bug 😊

Hi, thanks for the report.

Would you mind adding the whole backtrace? Also a smaller repro case would be handy; like a code snippet.

Hi @juanarbol 👋🏼

Would you mind adding the whole backtrace?

Also a smaller repro case would be handy; like a code snippet.

The minimum repro case is documented above, I wasn't able to make it smaller 🤷🏼 You need to run node from this repo, following the instructions above.
