Extension host stops in VSCODE

[TimSoethout]

I get this error message in the developer console when opening an argdown file in VSCode, or trying to visualize one.

extensionService.ts:457 Extension host terminated unexpectedly. Code:  null  Signal:  SIGABRT

Is this a known error? Or maybe related to other VSCode plugins?

Maybe related to this: microsoft/vscode#68024

As per mentions bug link, i downgraded to vscode 1.30 and it seems to work again.

thank you for finding this out and reporting it here, I was not aware of it. I have subscribed to the issue and will follow the discussion.

I can confirm Tim's report. The problem started to occur with one of the last updates of VS code.

The same issue has been observed and fixed here: ritwickdey/vscode-live-server#250

Looks like it's caused by the Electron and NodeJS updates in 1.31 (and above), which is why downgrading to 1.30.2 fixes the issue.

Judging by ritwickdey/vscode-live-server#267, ritwickdey/vscode-live-server@ca594e4 seems to fix this issue.

Thanks for the help! So it seems updating Chokidar/fsevents will fix this. I had planned to work on Argdown this week anyway so you won't have to wait long for the next release.

Same issue with Version 1.32.3 (1.32.3)

[christianvoigt]

Hi, thanks for the notification, I have just tested this myself. I did update chokidar in the last release (which depends on fsevents), but apparently at the time chokidar had not updated fsevents and was still using 1.2.7 even though chokidar did update fsevents to version 1.2.7 it does not fix this. There were a lot of changes in the last release, so I forgot to test this again. Sorry for that.

Chokidar has updated fsevents to the new napi version in 3.0.0-pre but this is not released yet. Not sure what to do right now.

@hevisko can you please go to your ~/vscode/extensions folder and check if there are two versions of argdown-vscode? In my case deleting the older version fixed the issue.

VSCode told me that it had updated the extension, but the error message was still coming from the old version. So I guess there was something wrong with the update process.
