Extension crash after last vscode update

[gandalfthegreydev]

Hi guys. Starting from the latest (or the previous one) vscode update, one of my extension crash immediatly.
I'm not a professional vscode developer, i did a fork of an existing extension last year, made a couple of changes and used it properly until a couple of days ago.

I would like to see why it's crashing, the extension host log doens't say anything useful except that is crashed.
How can I debug deeply ? I would like to know which line is crashing

Hi @gandalfthegreydev ,

For a deeply debug, you could try build and run VS Code itself, but its been a looong time I don't do this, even with weirdest errors while debugging my extensions.

But, I think regular debugging could work. You will have not only the Debug Console in your extension source but also the Console tab via Developer: Toggle Developer Tools command. Sometimes this Console tab says a lot about issues while initializing the extension.

On the other hand, if you are not sure in which VS Code release the error started, you could try installing older releases via the official documentation. Then, you look for Release Notes, trying to identify which news could have affected your extension.

Hope this helps

Does the original extension from which your forked yours is working properly in the current VS Code release? If yes, did you compare with yours to see what has been made since then?

the original works, but i've tried to remove all my changes and still crash. It crash immediatly, no time to open dev tool

Try starting a VS Code instance without your extension, open DevTools and then install your extension. Maybe something could appear in the Console.

Another alternative, start VS Code with no extension installed (via command line using --disable-extensions argument), open DevTools and enable your extension.

but without logging to file it's Impossible to read something. as soon as i activate the extension, vscode crash and close. seriously there isnt an option to log to file the debug console?

nothing useful in devtools, i can only see that the extension host is crashed.

Extension host (LocalProcess pid: 298411) terminated unexpectedly. Code: 139, Signal: unknown

ERR Extension host (LocalProcess pid: 298411) terminated unexpectedly. The following extensions were running: vscode.github-authentication, vscode.emmet, vscode.configuration-editing, vscode.extension-editing, vscode.json-language-features, vscode.npm, vscode.git-base, formulahendry.auto-rename-tag, XXXXX-MY-EXTENSION, lukasz-wronski.ftp-sync

Thank you for the hint.
The issue is that when debugging the extension, the vscode window crash almost immediatly and thus even the developer tools window.
Any way to log everything to a file ?
