• Version: v12.18.2
• Platform: Linux desktop-G31T-M7 5.3.0-62-generic fs: fix fd leak in ReadStream.destroy() #56~18.04.1-Ubuntu SMP Wed Jun 24 16:17:03 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
• Subsystem: Well, Unfortunately I don't know

What steps will reproduce the bug?

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

I know it doesn't make sense but, random. Actually I have no idea what is this error about, but there is a text "please report this."

What is the expected behavior?

It should run without any issues.

Additional information

I am not sure what causes this. I will try to find what is wrong with my code or maybe node. But I am using Typescript with VSCode.

[addaleax]

Yeah, it would be great to know the missing lines before the Cannot toggle Inspector … one – if this happens again, please share those :)

[selimrecep]

Just happened again :D Actually I have 0 idea about this I would want to provide more details. But the output log is all I know. I will try to find what causes error or in which scenarios it happens.

[selimrecep]

An additional note: undefined: 0 output part is not part of my code. Plus, somehow vscode try to attach debug twice (I guess): There are two Debugger listening on ... lines.

@selimrecep I think #34362 should fix this … I don’t quite know how to reproduce this, so I’m having a hard time coming up with a regression test, but if there’s any chance that you could build Node.js with that PR and verify that it fixes this, that would be extremely helpful :)

Either way, thanks for the bug report!
