Hey mate,

thanks for pointing it out and providing such a detailed bug report.
It seems to be an issue inside of that particular Node version (12.14 & 12.5)at stylizeWithColor (internal/util/inspect.js:340:27) and has been fixed with 12.16 already.

I am still investigating, so maybe I'll be able to come up with a workaround. However, you may want to upgrade to 12.16 in the meantime :-)

@deman4ik So it turned out to be a problem with some bright colors like blueBright, redBright. I checked the versions in question (12.14) and it works now, however not as colorful as on all the other versions < 12 and >= 12.16.

Thanks again for pointing it out.
