ArgumentParser exits when met with an invalid argument

[Kkcc01]

Hello,

I have been using your package for a project and noticed that when I use the parse_known_args() function, it exits when it encouters an invalid argument, even though I explicitly defined the parser as such var parser = new ArgumentParser({exit_on_error: false})
I don't have this issue with the python version but is it fixable for node JS ?

Thanks for your answer!
